Screw-in Rocker studs! Vortec Heads *Part #'s in description*

[@kiesha104]

Every Vortec head saved keep one of the 9 volt cars off the road...lol

[@Geoduck.]

As an old machinist I have to compliment you on the detailed explanation and clear video here. I would add one thing for those who don't know about taps. Use a four flute starting tap that is nitrate coated. The gold color tap is nitrate coating. A starting tap is tapered and will start much easier and tap straighter. I'll email you on the beehive springs soon.

[@lloydholt6511]

Just a little note Eddlebrock makes a stud puller kit and all pieces in the kit could be purchased separately at one time. It contained a pulling block, taps and spot facing tool for the studs which used the screw in studs with the radius base and hex head for tightening the studs. Like you, I always used a washer with rocker balls and one of the rocker nuts. Helpful tip would be a little never seize on the stud and washer. Now days most aftermarket heads come with your choice of 3/8 or 7/16 rocker studs. And yes always use a sealer on the screw in studs. If you don’t you will regret not using it. What your doing is almost a lost art. Thank you for sharing.

[@TargaWheels]

When I drilled and tapped my camelbacks at home, I free-handed it. If your tools are sharp and you don't force it, you can eye ball it. You can't drill and tap willy nilly. When you do it its best to pull one stud at a time and finish it, that way you can use the other studs as a guide (no special tolls, just free hand). The stud hole has enough depth that even if you're the slightest bit off, it'll correct itself. Just can't force it. And take your time.

Scary right? Haha and no problem! Thanks for the positive feedback Keep a eye out in the next couple weeks for a DIY vortec port job with flow bench results 👌

[@lloydholt6511]

In a stock configuration spring pressures on a stock head are not extreme, usually only 75-85 lbs on a closed valve. When valve spring pressures increase along with engine speed stock pressed in studs begins to pull out. If your lucky enough to recognize the failure mode and catch it in time engine damage can be averted. If your unlucky, engine damage can be mild to extreme. In the mild mode you remove the heads and install screw in studs. If you are not lucky, pieces parts get hung up in other pieces and severe damage occurs.

[@chrisdvorak8651]

Use anti-seize on the stud treads when pulling them. It will prevent the threads from galling.

Thanks for all the info you put out on the Vortec stuff! I am happy to have found your channel! I know this is an older video so dont know if you'll see the comment now, but have a question that I can't find info on anywhere I look. I have a 98 C2500 pickup that is the heavy duty option (12,000 GVW) it has L31 engine code but has the RPO code for 4 bolt main engine. Had to do an intake gasket a few months ago and pulled the valve covers. My engine has what appear to be threaded rocker studs factory. Have you ever ran across this before? They have a hex where they contact the boss in the head. Dont know if it is because its a 4 bolt main Vortec or what, but I know its all OEM still. Have searched a lot online and never found any mention of this from anyone else.

If I were going up to 415--427 cubes, then the 2.02" valve would be better, I'm thinking... I just want good, reliable power, for towing and pushing snow.

[@robertries7774]

Have you ever had one of the screw in studs snap? 60 miles on a brand new 383 and I followed you advice in setting up LS springs on the heads but I went with a Z28 spring. I double and triple checked the retainer to stem seal clearance and I had about .050" with the proper installed heights. It was idling in the garage and I heard a loud pop and clatter and turned it off very quickly. I pulled the pass side valve cover and found a rocker stud broken and 2 bend push rods. I pulled the other valve cover and found one more slightly bent push rods. I pulled the heads and there is no valve to piston contact. So I pulled the heads apart and every inner spring was broken. This time I'm going to cut the guides down and use LS beehive springs with comp cam retainers. The lift on the cam is .504". All of the pushrods had wear marks where they pass through the heads, you mentioned enlarging the hole in the head for the push rods...how big should I go? Yes, I used all new parts including long slot self centering rockers and .050 offset keepers.

[@cuttersperformance]

I have never have one break personally but I've seen guys break them when using stock rocker arms and bottoming them out on the stud, but you won't have that issue if your using long slots as long as the valve train geometry (pushrod length) is correct. So a few questions: You used regular Z28 springs instead of the LS beehives...where the guides cut smaller? Because the inner coil (damper) shouldn't fit over the stock large guide diameter on the vortecs and will bind up and break. Did you check push rod to head clearance at full lift? Its often a good idea especially with 1.6 rocker arms or high lift to drill the push rod holes in the heads to 1/2 inch for extra room.

[@robertries7774]

You are 100% about the inner spring. They went together with no issues but after the fact they did break, I had multiple broken pieces up in the heads and some stuck in the seals. I also think the fact I didn't open up the push rod holes is why they all were scuffed. They will be opened up to ½" and I will be cutting down the guides for good seals and a little extra retainer to seal clearance. I knew I should have gone with the LS springs in the first place.

[@cuttersperformance]

@@robertries7774 Yeah that's the problem man! Its good it happen right away and didn't do too much damage. And honestly the push rods probably hit because they were deflecting when those inner springs were binding. It pushed hard enough to break your rocker studs...you could imagine the stress on the push rods! Thats why they bend. Cheers! And let me know if you have any more questions

[@robertries7774]

I probably should replace all of the studs since I have it apart. I did manage to get the broken stud out by drilling and heat and an easy out. This is my first 383 stroker and damn it runs hard. I thought my 6.0 LS ran good. I'm 60 and I don't know why I didn't build one sooner!

[@sbf_fox2434]

Wish they made this tool for small block Ford heads. Seems like it would not be too hard to make

[@aldente3585]

What about pinning the studs? Used to be a thing. Yeah it’s not as cool but it would be way cheaper and accomplish the same goal. I’ve never done it but I’m thinking about it for my upcoming stock vortec upgrade.

[@cuttersperformance]

Yeah stud pinning was a popular practice years ago. I think once you try it you may realize why most don't like to do it haha the key is not to drill through the center of the stud but just hit the edge of it and thats easier said than done. Much easier if you have access to a mill Cheers!

Worth mentioning there is 3 types of taps. Works pretty good if you start with a starting tap then move to a bottom tap or plug tap. Bottom tap having the least amount of tapere. And not sure on truth but a machinist told me to clean the tap and cast with brake clean and tap without oil. Cast will chip away dry and oil makes it plug up the tap

sir have you even seen a SBC balancer seperate.. Im rebuilding a 4.3 chevy,, the sleeve on the balancer had a groove worn in it from the seal. I bought a speedy sleeve and put the balancer in the freezer for abt an hour to shrink the metal. I took it to my bench, installed the speedy sleeve and let the balancer come to room temp. I then took a rubber mallet and was getting the balancer started on the crankshaft. I noticed little pieces of rubber falling out, so I started hitting it with the mallet to take it off and the outer ring of the balancer seperated from the inner ring.,. so did me putting it in the freezer cause this? or was it just old and brittle.. the inner and outer parts of the ring seem to be glued together.. I was shocked that it seperated..

[@ljulian80]

I've had a stud boss break off a chunk 1/3 of the boss around and atleast a 1/2" or more down. Started doing these heads in winter of 19/20. Aggravated me so much I wrapped them up and shoved them in a corner, just now getting back to them in 22/23. What I have found is always use heat, always... I heat up with a propane hand torch then keep it warm with a heat gun. I also spray penetrating oil on the studs a day before and then again the day of pulling. As far as the broken boss I'm gonna put a bevel on it, heat it, wrap the head, weld it, wrap that spot then bury it in warm sand on my wood stove. Gotta cool it as slow as possible. I've never had a problem with welding cast and it not holding.

hi, do u have experience much spring pressure (open pressure) pinned studs can take? i have 416 305 heads which will be mildly ported soon..i would like to put screw in studs, but i fear of breaking the stud bosses when removing the studs..i have been thinking that pinning could be a bit more safe way as here in Finland, used SBC heads are unobtanium if i destroy the bosses and need to buy new heads. im going to put comp xe262 cam and 981 springs, and i believe press in studs cant take the the spring pressure if i rev the poor 305 sometimes to 5500

Rule of thumb i go by, if it needs more spring that a Hydraulic flat tappet than you should go screw in studs. (Typically over 120lbs on the seat or 300 over the nose)

[@mariosgbodys]

Whats the part number for the studs? You had said they were pioneer brand ?

[@cuttersperformance]

Ive had good luck with the Pioneer RM-348-16 rocker studs

[@jjmccloud]

Theyll pull out as long as they havnt sit awhile 😂😂😂 then I found out its a bit of work especially on the older crappy tbi heads

[@cuttersperformance]

Sometimes a little bit of heat works but I find vortec don't usually need that Cheers!

[@elliotrandazzo2094]

@@cuttersperformance what vortec heads are these? 906 or 062. Because ive heard that the tool for tapping doesnt line up on the 062 heads(sawtooth stamp)

[@crankyrancor2847]

Thanks for the great how to vid , just a question though , what brand and part# are the rocker studs you are using ? Ive have some ARP studs but need the stud bosses machined down to use them , using these will be a much cheaper alternative . Thanks again 👍👍

I have a question I have a 1991 C1500 and I want to do a vortec head swap and lt4 hotcam with 1.6 roller rockers. What do I need to do to the heads to make them work with my combo? Thank you

[@allisonsteven4600]

What if you pulled all the studs...?asking for a friend😂

[@Ryan............]

If the threaded studs look just like the stock press in, whats an easy way to identify if its already been done?

[@cuttersperformance]

You'll have to look closely for the rib on the stud that bottoms out on the head

[@cheol1250]

Can I use a set of self aligning roller rocker arms with this stud setup?

[@markmeister2444]

Would these Vortec heads work on a 283 small block? I'm looking at the cooling passages and I'm wondering if these and the bolt pattern will work. I've heard that the Vortecs will work on a 283 but I'm looking for a second opinion, thanks.

[@cuttersperformance]

Yeah they will, you can use both the 350 or 305 vortec heads on 283s and have great results over older head designs

[@markmeister2444]

@@cuttersperformance Thanks for the reply. I was going to use a pair of 461 2.02 fuelie heads I have but heard the valves would hit the deck, so it looks like I'll find a set of these 906 heads, thanks again.

[@cuttersperformance]

Yeah a 1.94 intake valve is the largest you want to go for a 283 as the bore size is small. 906 or 062 would be your best bet but even cheaper 305 vortec heads would work great too If i get my hands on a decently priced 283 id like to do one up for the channel with vortec heads one day 🤘

[@markmeister2444]

@@cuttersperformance I recently bought this as a short Block. Turns out it is out of a 1958 290 hp fuel injected Vette, still on the original bore, hard to believe. Looks like the pistons have been changed to a high compression piston of some compression of which I don't know. I'm going to go look at a set of 906 heads that supposedly only has 20K miles on them for $150,00. price sounds reasonable.

Will my stock rockers and hardware work with these studs I'm building a 350 with vortec heads with a comp extreme energy 268 I've been told it will be fine with the press in studs and I've been told to change to screw in studs

[@cuttersperformance]

Yeah the stock rockers will work perfectly with those studs...but to be honest most low lift hydraulic flat rappet cams the screw in studs are not essential. The more aggressive roller cams with heavy springs are what will pull studs

Great video. I have a problem though. I cracked an 062 head, bought a new one from OELINE, installed it. It ran fine for about 30 miles and up until I got it to 65mph. Then it started running rough. My mechanic said that one of my studs had started working it way out. He put locktite on it and screwed it down. Then when running he noticed it wobbling. Says I need another head. Why would this happen? Manufacturer responsible?

[@cuttersperformance]

Did the rocker arms bind up? Too much lift on stock rockers us a common issue

Do you have a good budget self aligning full roller or roller tip rocker arm set you recommend that will fit vortec heads ? I want to stay in a 1.5 ratio (aftermarket cam), and want to use incognito type studs in 3/8 or even 7/16 incognito style without machining

I almost always use comp cams roller tip rocker arms on vortecs like part number 1417-16. But I have used similar sets of the PRW rockers that look similar and haven't had an issue (they are cheaper).

Wanting to put the same studs in my 062’s are the new studs the same height or close enough as the old ones once installed?

They do make different length but the ones I use are just slightly longer and fit under the stock covers no problem
