[@bowtiedone2784]

I'm so glad you made this video. I get so tired of explaining this to people who think their tpi heads are the bomb or call them "vortec" heads. From now on I'm just gonna send them this video and tell them to learn something 👍🏻🏁

[@jamielunsford1]

Amazing content! Thank you so much! I was raised a gearhead, joined the navy and had a bunch of kids, and now I'm retired from the navy and working as a contractor in Iraq. Your channel is invaluable to me for gaining knowledge in preparation for coming home stateside where I will finally find and build a 60-66 C10! Thank you for the knowledge and the in depth explanations.

[@SD-pi9co]

BOOM!!!!

[@Sonos45]

In 2019 you can get bare aluminum castings from china with 200cc intake ports for less than $200 each. Good times man.

True

[@MechaNick03]

205cc now, 180 dollars

1.94/1.5 “valve heads CAN be run on a 305 block. I’ve seen it done and have done it myself. I have stepped up to 350s in all of my small block projects, but I give 305s credit where they are due. If you have an extreme budget, a simple heads+cam 305 is a great choice for a little 300 hp runner. Milled Vortec heads and mild .500” lift hyd.. roller cams work great on them with 9:1 compression. I did it and made about 325 hp in my old IROC with a COMP XR270HR. Still wasn’t enough for me, though. 305 HO ‘601/416/081 casting heads work great on 350s as well. With a .039” head gasket and the 58cc chambers, you get 9.9:1 compression. But that gets you nowhere unless you port those heads, and in the case of a ‘416 casting head, can grant over 220 cfm hand ported. Easy, cheap 375 hp engine if you run a well-matched cam. 305s in and of themselves are not good, but their parts are if they are applied on the right combination.

[@20alphabet]

Lol, "extreme budget" that accommodates your listed modifications... but not a 350 short block? 😆👌🏼

[@limabravo6065]

I had a 305 in an 86 Z28 and I had a budget of $2500 for my engine. So I picked up a vortec 350 (2 bolt) from summit @ $2200 and an intake from professional products. And since the car was carbureted from the factory I wasn’t changing anything major and man what a difference 95 extra horsepower makes. Since then I’ve installed ls6 valve springs and an eBay lt4 hot cam and the car dynoed at 240 hp at the tires, doesn’t sound like much but when you figure drive train loss through the 700r4 I’m making stock ls1 power for less than $3000. Now I just need a stick trans and it’ll be “done”

[@markschmitt5550]

TBI heads work well for a truck with an RV / Torque Camshaft, like the affordable Melling MTC-1, and a small vacuum secondary 4 barrel with a dual plane intake. You'll have all sorts of torque with great drivability. The camshaft curve is idle to 4,500 rpm and the TBI heads flow to 3,500 / 4,000. I've built several truck motors with this combination that pull extremely strong with great fuel mileage. It's all about what you are trying to achieve. If I was building something with more mid and upper range RPM oomph, JEGS and Summit Racing both have brand new heads for low $300ish each. They offer an old school 2.02 intake valve, 72cc chamber, head and a Vortec form factor.

[@leviscott8519]

From Jewel to diamond! You are a mastermind engine builder. Thank you for your great teachings! Build on!!!!!!!!!!!

[@stevenlocke4769]

I'm glad I watched this. I just bought a set of Vortec heads to put on a 305 just to help it a little for my nephew's first vehicle. So it looks like we're going to refresh everything on that engine as a learning experience. At least I only paid $75 for the pair

[@DallasMoss]

Thank You for putting together these videos! Very informative!

[@antwainhuntersr.4459]

Your videos are AWSOME bro!!! Very educational to a beginner like myself.Thanks a Million!!!

[@kyleguinnip214]

Thank! I just almost got a set of "vortec heads" a guy thought he had, turns out they were tbi swirly heads. You just saved me 200 dollars and a bit of headache.

[@monkeywrenchization]

One thing you forgot to mention is that on the right side exhaust manifold rear flange is that sometime in the eighties they made the bolt pattern wider on the rear of the manifold. Earlier heads did not have both bolt holes, so trying to put earlier heads on a later engine could cause problems fitting up the manifold. I learned this lesson the hard way. The rest of your information is very good.

[@jthor3277]

This is the best! Thanks for your time man!

[@FairytaleVideobiz]

Great videos I use Sportsman 2's but I love listening to someone with knowledge about this stuff.

[@tlbawheelspin630]

These video's rock; you're just like my old shop teacher, super easy to understand. Really helping my project along.

[@forgotmylogininfo]

THANK YOU!!! I am tired of people arguing with me that the different angled bolt holes were vortec. I had one guy argue with me for hours, he spent his money on stuff that didn't work.

[@chuckmarquart]

I'm a Ford guy but loved your video very informative keep up the good work

[@chevywilliams958]

Im looking at a 350 crate (260hp) off summit website for 86 caprice. Im going to order vortec heads, correct intake/gasket and comp cam xe 268. Is this all i need or im missing something? Want to order everything i need all at once.

[@MrLostonej]

So I have a question about the 624 truck head off of a 400 ,,does it have hardened valve seats. and can you do a 400 head best and worst. thanks

[@adamantium1983]

Just picked up a pair of 062 heads last night, on the shelf they go for a future project.

[@Johnoines]

I bought new vortec heads from Chevrolet in 2003 for the carburated 1981 350 that I was building. They performed very well. But they had one big drawback, because they did not have heat riser passages they are very cold blooded and don't run well unless you run carb heater hose to your air cleaner (or some other type of carb heater) if you expect to have your engine run right if you live were it gets extremely cold in the winter.

[@anthonytoler718]

Great video! I have a question. I would like to know whats the best aftermarket heads or one of the best heads for the TBI engine that have the same bolt pattern. That flow as good or better than the Vortec heads with out giving up any torque on the low end. And keep the same compression ratio.

[@V22D]

Greate video I have a question can. I put vortec heads on my 95 chevy 350 tbi whitout upgrading anything els? except for the manifold nd whats a good brand to buy a manifold so I can put my tbi back.thanks

[@mann31313]

First off great job on your videos I've watched several so far and they're very informative! ! I was searching through your videos for any information on heads, engine builds or anything else relating to a SBC 400ci. Do you plan on making any videos on it?

[@ScaleCarModels]

Great videos thx for sharing all this info!

[@dieselmanmike]

Great video. I have a 74 Camaro 350 engine with an eidelbrock performer intake with 4 barrel carb, middle bolts missing and 4 in the middle on the covers so I am assuming vortec and the cast exhaust manifolds that curl up (ram horn?) and I presume from the smooth idle a standard cam and my spark plugs are toasty brown and she runs sweet. Any idea what hp I may be getting from this setup. I’ve just bought the truck a 56 Chevy pickup and it really does move well ! Cheers for any valued advice.

[@melvinnewsome6821]

Thank you, this has been verrrrry helpful.

[@tinacay]

Awesome video! I have a 1972 corvette, I want to put some better flowing heads, looks like I'm going to start searching for some vortec heads. My question is, will the heads have all of the same bolt holes on the front for the accessories?

[@roachsrods4395]

The 193 tbi heads actually respond very well to a straight pattern cam they flow pretty well on the exhaust side. The swirl ramp in the intake runner is the main reason they suck.

[@rosscairney5375]

I’m going to look at a pair of Vortec heads tomorrow. (Or at least that is what he is proposing they are). I have watched your videos (they are awesome) so I know the casting numbers I need to be looking for. He says he “just got them back from machinist” which I am sure is a giant load of BS and I’ve noticed there are a lot of blocks and heads out there for sale that “just came back from the shop”. What should I look for??

[@williamhenley2740]

Love your vids keep them up.

[@mcofield2291]

Thank you for sharing your knowledge.

[@randyrowe3097]

I rebuilt the motor in my 99 classic Tahoe. The heads were cracked. I replaced them with some summit vortec heads. Was told they were made from dart. I put an lt4 hot cam in with longtube headers. It runs good but not dialed in. I replaced the spider injectors with the better factory upgrade. 411 pcm which is somewhat right for the build. Deleted the emissions stuff and such. Anyway the larger tb's in the aftermarket is really expensive and limited. Want to swap over to a carbureted intake. What intake and carb would you recommend for a fairly mild build such as mine?

[@bnetolldnataman]

Love your work Bud..Thanks for the info.. Got some 906,s with a 350 bottom end for $50 aussie.... man am I cheering right now!!

[@Classickoolcars]

Thief. 🤣🤣🤣🤘

[@junkyardjohnny959]

Great vids awesome info. keep up the good work \m/

[@jimdavis7714]

just remembered the 7 hole Heads and the Spreaders built in on the Exhaust Manifolds of the older setups in cars like the Caprice and some cars coming out with 4 bolt blocks like the 3970010 or trucks 397001

[@souprchrgd]

Talk about your crash course in chevy head identification! Great info!

[@leogray146]

hello I have a set of double hump heads that are 2.02 valves 76cc(I think, sure about the valves though) they do have accessory holes from the factory. can you shed any light on them. I looked up the numbers on them once and all I could find was that they were aftermarket gm heads made in mexico. are they any good? they do have screw in valve guides but I think they were done in a machine shop.

[@jwmahin1]

Any recommendations for spark plugs for the Vortec 906's? Great info. Thanks

[@dfinkie]

INFORMATIVE! Thank you.

[@LandonRoy-cv9rt]

Agreed, my buddy spent thousands on intake manifold, cam & springs, exhaust headers, carb and ignition in his goody Cutlass...I dropped in a 97’ vortec L31 with only a small Comp cam and aluminium intake just so I could scrap the TBI set up to have a carb which I installed a Quadrajet in my 4 door Buick Regal body, we both has 1 wheel peelers and I’ve smashed him time after time after time even allowing him a car length off the line and I still over take him within a few seconds, I spent maybe $1000 on everything motor, cam, intake, old ass carb and swap, he’s spent thousands around $350 and I make him look stupid with that 305, if I slapped in a bigger cam and springs it would be a joke. Stock junkyard vortecs have rollers cams, 4 bolt mains, 1 piece read mains, awesome flowing factory heads and the center bolt valve covers NEVER leak

[@mikewoods1650]

Hi, thanks for the videos. Can 186 heads be used with tbi? I know you recommend vortec heads, I can get these for a good price. Thank

[@Myvintageiron7512]

Yes it refers to the swirl effect the ports have on the air charge

[@DjCBlaq]

quality videos man. top shelf

[@MrHootenholler]

I have a 1994 c1500 tbi and would like to upgrade cam and heads for a little more power ...nothing crazy .. i want to keep stock tbi system .. is that even possible with the computer stuff

[@ericrivera744]

very informative. this is exactly what i want to do. what cam would you suggest with those heads. looking for power gain. i am investing in heads and cam in my 88 c1500 tbi. i

[@kobeebeatty2965]

And also. Do you think that not having any bolts in the middle of the head to hold the intake manifold down is a flaw in vortecs? I have replaced two lower intake manifolds on vortec trucks. Getting to be a pain in the but if you know what i mean. Thanks

[@kobeebeatty2965]

Ok. What heads do i find that i can put on and utilize the stock intake manifold and tb unit for a tbi truck? A guy i know who restores hotrods and good stuff told me the stock intake and the throttle body unit is actually pretty good. The reason why tbi trucks are dogs is because of the heads and the crappy y pipe. Thanks

[@highwaystar8310]

Thank you great videos on the heads now I know what to look for!

[@AshZiavonni]

What info do you have on engine block w/ casting no. 46077823 (HP/torque)? What production car or truck was it used in? Now that's on the rear driver side of the block. Dumb question...How do I find out what heads are in it? >What are the possibilities of heads that could be used with a 305 block (stock and also 'bored' etc)? < I noticed at least 3 drilled holes on the side of the heads where belts run...though current set up bypassed with no bolts or pulleys hooked up. The engine runs w/o accessories ac, ps etc.. Also, is there a way to know what internals were used in the rebuild?Used car motor swap ... .no idea. Sounds like a beast with tons of power though....which makes it perplexing.

[@Hapfletcher]

love these videos...im learning so much thank,,I have a 327 ci with 1.74 power pack heads now...I know small right?..but I just slapped them on to hot rod around town, but as I drive it more I see at about 4500-4700 it drops of in power. would I really notice a difference in a set of 2.02? I don't race it

[@montrosepatriot]

the drawback of the TBI heads - they have swirl ports (first introduced in 1983 on the Cavalier 2.0L motor) designed 4 max fuel economy - the swirl ports produce a tornado effect (hence the Vortec nomenclature which was introduced in 1985 with the 4.3L); also, the 96+ Vortecs (used on the 4.3) - there is no aftermarket intake 4 the TBI or CPI setup which exists

[@Myvintageiron7512]

Are you talking about aftermarket 4.3 Intakes? or 5.7

[@montrosepatriot]

Myvintageiron7512 4.3L (the only aftermarket TBI intake which exist is the Edelbrock 3713 for use with 85-95 4.3 TBI - the 3713 does not have a Vortec 8-bolt pattern)

[@Ryanbramlett12]

Great videos very informative

[@ghostrider-pm5gk]

I have torn down a 350 and it seems to have 2 different heads. an 882 and a 388.the 882 has dropped a valve and cut its way into the seat.the engine ran rough as hell before I tore it down.I think its because of different sized valves and/or more compression on the 388 side. it looks to be shaved. what is this 388 head?

[@stewartfalk1977]

How are 032 Heads? Got A 307 bored 0.30 thou, original edelbrock performer intake and will be running a 400-600 cfm carb

[@martinaleman7982]

I have a 93 chev 4x4 with a 5.7 L with TBI and a 4L60e trans. What would you recommend in terms of heads, manifold; carb to get 350 hp?

[@redelmo39]

thank you for your information,

[@badmonkeybushcraft4229]

Great vid. Thanks for the info.

[@Stars-us4gh]

Question I have a 2000 GMC sierra with old body style that is 1999 with Vortec 5.7I watched your video and you said 96 and up I believe should be true Vortec heads .my exhaust that goes into the heads have 6 bolts ? but that is not the manifold side , so do you know if my exhaust is supposed to have 6 bolts that go to the head ? to make it a true Vortec. maybe a stupid question , sorry in advance.

[@MrCbell57]

Sorry I missed that you had a second video part 2 from the first one on heads. I think you answered my question about heads #191. All I need to do is find out if I can cap that water port on the drivers side or find out what I need to do to keep it working. Thanks!

[@Bizzhatesme]

Would you mind discussing 23° heads in an additional video? Great videos, I really appreciate the knowledge.

[@jimdavis7714]

i have no experence in the TBI -TPI and vortecs , i would have fell for the vortec fakes not knowing , i dont use craigs list ,,, Thanks for doing this vid :)

[@Hemi-gc8zg]

Great video with great information and great explanation

[@JJDaCool1]

hey Myvintageiron7512 great video on stock 305-350 heads and if you mind me asking which aftermarket heads would you chose on 350-383 application its going to be with streetable cam also nothing crazy.

[@waynew2831]

Great series on SBC heads. I learned a lot. I would like to know your opinion on the Pontiac 389 motor for a street build. Not for the track, but at least competitive on the street. Thank You

[@thecatfelix2988]

Great video . A lot of good info . i have a 1986 gmc with a 454 . do they make vortex heads and carb intake for that old 454?

[@vintagedashboard6810]

I bought a set of 441x heads and was really interested to see what you think about me swapping the 882 heads for the 441x heads and they have been pocket ported and the valve guides have been blended and look really nice and also they have bronze valve guides. Gary in Texas also I only gave 100$ for them.

[@rodschweiger4195]

My son has a vortex head (no center bolts) 350 crate motor from Summit in a 1972 Chevy pickup. He bought an Edelbrock intake and it keeps sucking intake gaskets (twice now) into the valley causing a massive intake manifold leak. Any ideas on what we did wrong? Rod

[@dougsalsbury3300]

thank you. this cleared it up for me

[@oneforliberty]

How does the vortec heads compare in flow numbers to the old reliable 461 or 041 heads?? I have 3 sets of these vortec's that I have never built up to use as of yet ..But I'm planning to very soon..

[@88gtman]

Would love to see a part 3 covering the later LS/Gen III heads!

[@jakeschumer7021]

Within the first 5 minutes he shits on the 305... I like this guy

[@sparlin88]

So after watching this the 69 El Camino I bought and am building has The 4 intake bolt heads . I also have a motor with 186 heads . Which would be better to use to get mot street Rod performance . I'm not a engine guy so what i know if from You Tube . Thanks

[@jonpeter78]

Hi.I have a 350 block 89700010 and am running 3911032 307/ or 327 heads. Is this what they used to do to them for higher compression?

[@leebornaman5508]

Wow. I was just about to buy a new 3o5 crate motor to put back in my 98 c1500 2wd truck. A direct swap part for part. Now I wonder if a good 350 would be a better choice. Thanks for the great and detailed videos. "Born the same year as the Corvette"

[@bobbefumo2306]

Definitely go with vortec ,350 world of difference don't forget to use a ECM for a350 good luck

[@jimdavis7714]

also could someone post about using 400 SB heads on a 350 ok and 350 on a 400 not ok because of the Center Steam holes between the center Cylinders

[@Dodgeram591]

Great video!

[@jeremypestano4076]

any recommendation for 1984 c4 tbi upgrade heads thank you!

[@jimdavis7714]

i was wondering if someone will post a segment on Small block heads tht will be used on Propane Gas ,, its a Dry Fuel that Requires Very Hard Seats or the Valve will Suck its Way into the head or pop the Valve Head from the Stem

[@austin1995march]

i have a 350 lt1 block from a 95 trans am what should i use for heads

[@erichoward8463]

I noticed that the aftermarket intake manifold that you showed us had 2 thru holes in the middle of the intake-to-head mounting flange, but only on one side. What are those for? Just curious.

[@17buckrogers]

i have a 99 chevy suburban 350 vortec stock with about 200,000 miles having the heads rebuilt give it more power or do i need to rebuild the engine too?

[@buddyblankenship3444]

hey myvintageiron, just a review on what I asked I actually collected two pairs of 993 heads, I have one set cleaned lightly ported and all new 500 lift springs retainers locks and seal, these are going on a 9:1 350 4 bolt main, comp cams extreme energy 268 477/480 lift hydraulic cam, professional products intake and a Manuel choke 600 cfm holley carb, 65k dizzy and msd wires, question is will this be a decent combo for this head, compression is factored in with the heads being 76 cc btw

[@Ken-wu2bf]

Love the informative videos! Where do you get the studs for Vortec intake manifold? It's a great idea.

[@noelmedina4915]

I have 94 tbi trying to see should I put 305 head a push compression 10:1 or vortec heads???

Yep that's in part 2

[@tjvillan69]

Awesome video keep em coming! I have a 96 chevy k1500 that is a project truck. Due to California smog laws I can't upgrade the motor to much but am wondering if there is anything I can do performance wise that won't conflict with the smog laws out here! Anything will help thanks!

[@tjvillan69]

Yeah no thanks been their done that I'll stick with the west coast! It rained more than enough this winter as a matter of fact it was record rain fall since the 80s. But that's beside the point! Got it handled already got it registered in Clearlake, Ca which has no smog laws.

[@timharrison5500]

Thank you for taking the time to make these videos! I have a 79 C-30 That I am wanting to pep up the 350. I currently plan to make it a 383. I recently pulled the motor and after watching your video I tried finding the #'s of my heads but haven't located them yet. Are they marked externally? Thanks again.

[@Myvintageiron7512]

the numbers are in the rocker arm area

[@16Havens]

what is your take on undercut valve stems? any significant difference?

[@kerrycane292]

Love the information on heads .can you me what are the best flow numbers from 186 heads and can they support 500 hp or more .I was told they could with some machine work .

[@jefferybagwell5307]

Would 441 heads be worth putting on a 406? Over 882 heads? The 441s I just got and they already have screw in studs while the 882s don't. In the end which would be better flow wise and everything

[@265chevy]

thanks for posting
