Small Block Chevy Cylinder Head Rebuild - Valve Grinding - 3 Angle Seat Grind - Measuring CC's

[@DeliriumElectric]

Brilliant. Gotta love old tools that still get the job done

[@rideupsidevideoadventures3172]

Hey Mr. Jayhawker, Don't think for a minute that your videos are to long. The details behind an engine build can not be explained in 15 minutes. I've been working on cars my whole life. Like you I also want to keep them close to original. My first car was a 1967 Mustang GT. It had 27000 miles on it when I bought it, however it was also only 5 years old... yep that was back in 1972. That's a tell there now, I'm not 35 either. I love your videos man, keep it up. 😉🏍

[@larryburns4605]

As. iC weld says it's not how to do it, but the way I did it . Great videos

[@randallsanders7446]

Great video! And, yes, I'm over 35. I have read books about the process you did & I have seen pictures of the equipment you used. But, I've never seen it done & haven't tried it myself. Seeing it done helps give me a clearer picture of what takes place -- book learnin only goes so far. Also appreciated the closing comments -- FAITH is #1.

[@TheJayhawker]

Thanks so much, I've been trying for years to get back to the point that I can do this work myself again. Always learning, and in my case re-learning.

[@larryburns4605]

I use 305 heads on 307 , 327 alot but open chambers up to bore diamater work great

[@codewarrior65]

Nice video. I worked as a mechanic for 20 years or so before going into Computer Science. Working on a 327 L-79 build myself right now. I like the old vintage SBC stuff, mainly Corvette-inspired engines. I do have a DZ 302 engine, maybe someday will build it. Yes, I am way past 35. LOL

[@JohnnyBfromPeoria]

You had me, right up until the end. Engine building and religion...I just don't get the connection. Pick one or the other for videos on You Tube. Cool old equipment, too. How you research and find parts or work-arounds is impressive.

[@TheJayhawker]

You may regret the comment but I certainly appreciate it and I appreciate your watching the video. I’m a quiet introverted guy that likes to do things his way and doesn’t like anyone looking over his shoulder while he does it. A few years ago, God really started challenging me to start making videos, which I refused to do. That was about the worst form of torture that I could think of. In fact, it still makes my blood run cold. After a little time, I finally relented and began to publish some. So now anyone the world over can look over my shoulder and tell me how I’m doing everything wrong. Yikes! I decided when I started with videos that I was not going to do it without Him. God was asking me to do it so I was going to do it with Him. Typically, all I do is a bible verse during a 20 second clip at the end of every video. If this is offensive it is easily skipped. But I would certainly ask myself why it’s offensive. Oh, and with a Christian, it is not a religion. It is not a do this, this, and this to cover your butt and you’ll be good to go kind of thing. It’s a relationship with God, the one who loves you most. Plain and simple. Thanks again for watching. I’m not sure any of this will make sense to you, but with me you get both or nothing.

Great videos. Very informative. I’m a little older than you ( I’m actually 4 years younger than dirt ). I picked up a 68 GMC K10 Stepside with a 307 several months ago. The motor actually runs great but I also have a 65 327 sitting in storage that I was considering going through and putting in the truck ( also have a 67 283 )…as you can see, I have several options, just not sure which route to take. It’s good to watch someone go through the rebuild process in detail. I find it satisfying ( I’m an Industrial Millwright by trade ). Keep up the detailed work…don’t shorten any videos ( the 20 somethings will go back video gaming after 20 minutes anyway )

[@TheJayhawker]

Sounds like you have some fun ahead of you. I have a 307 on the shelf as well that I discovered someone put 4 bolt mains into. Very unusual in my mind but it would be fun to play around with. Thanks for watching!

[@oldmanintheshopbuiltnotbou8726]

Man I've got black and decker valve grinder and I love using it great job

[@stephenmanion3418]

NICE work MR SBC.!!!!!

[@dustcommander100]

Another great video! And an uplifting ending, too!

[@timothyrdunning]

really enjoyed your video and i agree it is interesting to go back and use the old way tools. I found it interesting the way you worked out the compression ratio of the engine with your good explanation. ☺

[@kevinpfaff2301]

Another great video. The way you explain things is just so thorough and makes it easy to comprehend. Thank you so much

[@ezelk1337]

I stumbled across your channel and I love it. I am a 63 year "Old School* guy that used that same machine in high school Auto shop to do a valve job on my 56 Chevy. Didn't do a 3 angle valve job. I probably forgot if he talked about it but I thought that it was for performance only. But it looks like it is the best of both worlds. What a great explanation!

[@TheJayhawker]

Thanks for watching, glad you found me! What model and what engine was the '56?

[@ezelk1337]

@@TheJayhawker it was a 2 door 150 model business coupe. It had a 235 six with a 3 speed with overdrive. My first car. Cost $225. I rebuilt the front end totally. New paint and homemade upholstery. Hopped up the 235 also. Headers and 12" Smitty glass packs. It was loud! Oh I have Prussian and Swedish ancestors also. You do very nice work on everything. I will keep watching. Eric

[@kraigkenyon417]

The "young bucks" and "must be over 35" are starting to make me question if I grew up in the right Era! I mean I'm 28 so close to 35 but I found your channel last night and watched the whole 327 build.

[@Texassince1836]

350 Vortec heads would work out great on a 327, 1.94 intake valve 64cc chamber, and great flowing intake ports

[@mygarden365]

Thank You,I learned something!

[@aintskairtolskol9520]

amen my brother

[@amazin1827]

Those old umbrella seals would CLIMB THE VALVE and let oil down the valve guide. The spring seal holds the valve boss staying down on the casting. A fine gypsy woman once told me I had RUSSIAN HANDS and ROMAN FINGERS!.... Do you love the Great White Hope??. Watch JLP to find out! AMAZIN🇺🇸

[@richardlucy3822]

Awesome video good info

[@richardlucy3822]

Amen brother!!

[@tubedude4859]

i have always considered 305 heads like shortness of breath . Get a few bucks for scrap iron

[@TheJayhawker]

Most certainly were, but not certain truck heads.

[@Mike-xt2ot]

I have a set of double hump heads with no accessory holes on head. They are closed chamber 64 cc. One casting is 461.and the other is a 462. I pulled them from a 68 chevy C10. Let me know if you'd like to put the original type heads for your 327. I realize it's been 5 months since video was on KZbin. Just a thought.

[@Tims13ful]

Static C/R. verses Dynamic C/R. Cam duration is the key to running high static C/R.

[@anthonyalvarado5899]

5.7 Vortec heads are good depends what u want

[@Davinci12007]

Love this build! Might sounds crazy but from someone who's been grinding for 45-ish years, your grinding wheel sounds dull. But then again, it's probably the high quality -lack of - dolby sound that KZbin doesn't offer. Anyway, I still love the build.

[@TheJayhawker]

I would trust anyone and their ears if they have been grinding for 45 years. Thanks for watching and I hope I did well!

[@graydonjones6912]

I don't understand why people are afraid of higher compression ratios just pick the right camshaft and your good to go ,just go look up David vizard and he explains it all

[@steveamnmn]

Respectfully I do have to agree with another poster here who mentioned the .087" quench clearance. With ~9.6 to 1 compression and iron heads you'll likely have to pull so much timing to prevent pre-ignition that it will really compromise power output and fuel efficiency. Of course, you could run longer cam timing to lower dynamic compression, but that probably doesn't make sense for a truck motor that needs low rpm torque. As mentioned, .040" quench would be more typical, and even .035 quite acceptable if the decks are square. The tighter quench creates so much better mixture swirl and tumble in the cylinder that...even though it further raises compression...it nevertheless tends to discourage detonation better than a lower compression with excessive quench. Probably the best solution would be a piston with a taller deck height to tighten quench and a deeper dish to moderate the compression ratio. All that said, I really appreciate your videos and fully relate to doing the best you can with what you have! God bless.

[@95Z28A4]

And you could add "learn how to read an analog clock" for the 35-year olds. :)

[@williamkroth9429]

Is the valve seat grinder slowly "orbiting" on its own or is that from the operator? Excellent video!

[@TheJayhawker]

Yes sir, that particular grinder operates on an eccentric.

[@williamkroth9429]

Thanks, it looked too precise to be orbited by hand. I learned a lot and I thought I knew more than I actually did!.

[@larrywarner9314]

If I was you I'd would unshroud those combustion chambers you'll thank your self down the road

[@graydonjones6912]

You want the teflon valve seals that lock onto the top of the machined valve guide all the rest are outdated junke especially on Chevy small blocks

[@robertlynch7068]

Perfect love casteth out fear 1st John 4:18

[@graydonjones6912]

Im sorry but I would have turfed the valves for new ones especially when you ground the hardened surface of the valve stem

[@Bill-xc8le]

Get the thickest head gasket felpro makes if you wanna knock the compression ratio down.

[@68RatVette]

Bill, read up on QUENCH. You can see that the pistons are WAAAAAY down in the hole...looks like .040". (found out .046" was his measurement) Much like the 327 in my 1968 Camaro (more than my Camaro as it turns out). You want to run around .045" quench (distance down in the hole plus head gasket) so a thin head gasket or deck the block. If you quench is way off, like running a thick head gasket as you recommend with pistons down in the bore, the air fuel quench will be less than ideal...less power, less mpg, more emissions.

[@Bill-xc8le]

@@68RatVette if you want it to run like shit, your way is the best!

[@joshstaley7459]

no lapping?

[@TheJayhawker]

Because I did an interference fit only the thin line at the top of the valve would get lapped and if anything it would tend to wear the faces into the same angle right away.

[@joshstaley7459]

@@TheJayhawker makes sense. my high school shop class had the same exact valve tools you have there, our teacher would have us take apart a cylinder, grind the valves, grind the valve seats. i had forgotten all about it until i saw your video pretty awesome stuff.

[@joe-hp4nk]

You met my wife.

[@davideldridge2537]

Your quench is over .080 way to much. Should be about .040 with that much quench clearance it will be more prone to detonation
