Nice work Joe, I know that is takes alot of time around the valve guides. I definitely have something to work with for sure. Thanks for sharing the process. 👍 Thanks for the shout out. Have a good weekend.
Great respect to you engine builders that port, increase valve size, reshape combustion chambers etc. Pretty fiddly and tedious work. I don't have the patience for it. But cudos to y'all that do. That's why I see your tail lights...lol.
Nice work Joe! Glad to see you diving into another set for people to watch and get inspired by! This will be a fun series to watch, and I look forward to watching what Ed does with them, as well.
I used a set of '308- casting' 360 heads on my '76 318 in my Valiant. The factory machining was so bad (the car was an original 88K mile car when we started), that the decking required to clean the top end up turned the KB pistons into pop-ups and would have over 10-1 compression ratio with the 308 heads & stock head gasket thickness. With 0.060" thick Cometic MLS gaskets, the compression ratio ended up being 9.45-1, so pump gas was viable. Heads? New guides, exhaust valves, multi-angle valve job and a little cleanup. It's not a race motor, but it's a very nice street performer that isn't finicky.
Looks great. If you ever get a tiny but nasty spot you can not get into. They make stones in 3 different sizes for your dermel for sharpening chainsaw chains That may help. Hood luck with the improvements.
Nice job Joe! I just did my (302) castings for my 318, and that long valve guide in the intakes is a real pain to get ground out of there! I need some of those long shanks.. I’m sure those definitely help
I would definitely gasket match the head , start at your line and roll it into the port no need to hawg it out , will definitely make a difference in low to mid throttle.
I gaskets matched both heads and intake on my 318. My thoughts are bevels flow better just like the top of a velocity stack and you can take a good amount off the push rod pinch. I also opened my intakes up to 1.94 valves.
Nice work and very instructive for me. I want to overhaul my engine next week and also wanted to port the heads and file away the heel of the original valves. Does that help or can you neglect filing the valves
Hey Phil. You can definitely see a gain by backfacing the valves. It’s usually a simple and inexpensive process at most machine shops. You can do a version at home, but it’s often time consuming.
Mr Mopar 64-66 barracuda, Can you tell me by chance which had a chrome script that read Bumblebee? 🤔 I saw it personally.. It looked like a regular ol valiant.
That’s a new one on me. I’m behind in many areas of Mopar wisdom. That will come with time. I would check the forums and Facebook groups to see if anyone has an answer.
you don't want the throat to be the same size as the bowl on the other side of the short turn. you need the bowl to be bigger. if it's a straight shot like yours, you take away the venturi effect and kill low lift flow, big time.
Thanks for sharing. I understand the principles there. My bowls are slightly wider than the throat. Ed is cutting new seats for larger intake valves and then blending them as needed in to the throats. I will show some better measurements next time.

Thanks for the shout out.
Have a good weekend.
Thanks, Ed. I’m excited to see them after your finished. This will be a top notch set of factory heads!
There's something very therapeutic about watching ports get ported! Good times Joe!
Thanks buddy

I appreciate that. Trying to get better each time!
Watching that gave me PTSD from going through the jacket by the guide boss. 😂
Ouch! I told you, if I had only known! Lol

More to come! Thanks brother
Great job and those heads seem a bit rough around the edges 😊. But, I'm sure you'll get em lookin like a couple a shiny new pennies 😊
Fingers crossed! Thanks brother!
Good job,those will flow great when all done for sure! Those are the Same casting number heads thats on my Challenger 😊
Oh man! We know what yours will do!
@JustMoparJoe Yea they do a pretty good job for what they are lol 😊
Ya Joe 👏🏻
Thanks brother
They look nice ...... hope to see the finished product after back from the machine shop.....great content as always Joe....thanks
Thanks 👍 I’ll definitely showcase them after final assembly.
Doing a great job, Jo ,thanks for sharing,,all the best to you and your loved ones
Thanks Donald! Hope to see a racetrack tomorrow 🫡
Keep flowing the MOPAR info Joe we don’t want brand X in front of us . 👍🏻🇦🇺.
Thanks buddy
Nice port work. 😎
🍟
Thanks brother
Nice !!!
Thanks Tim!

Thanks for sharing. It sounds like I have a similar plan with these heads.

Thanks Stan! I have a few stones. I’m usually a burr guy

Thanks Ryan. For sure. Love the long shanks! It’s a game changer
Great job joe has to improve the flow for sure.
Thanks brother. Ed will make them top notch!
Good job.
Thank you!
I would definitely gasket match the head , start at your line and roll it into the port no need to hawg it out , will definitely make a difference in low to mid throttle.
Thanks Brian. I’m going to port match the intake to the heads on final assembly. That way I can double check roof alignment.

I agree with you! Thanks for sharing. I will definitely gasket match the intake to the heads before final assembly
Another fine example of your mechanical wizardry Joe! All told, how much time would you say you spent on both heads?
Thanks Mike. I would tell you, but it’d open up discussion for someone to scrutinize. I’ve been told I’m too slow in the past.
@@JustMoparJoe You are meticulous , not slow Joe. BIG difference.
👍 👍 👍 👍
Thanks brother
Nice job, Joe.... How many hours do you think that took???
Thanks, Steve! Shoot me a message and I can explain my process.

Hey Joe, I'm asking because I don't know, not questioning your work. What makes this a smog head?
Hey Brad! I used this term because it wasn’t and X or J head. It has the smaller intake valve 1.88 versus the 2.02 of the performance head.

@@JustMoparJoe Please pass it around your connections & see if they know, You'll probably need a baby boomer type crowd. 👍
Those castings look very rough or had terrible rust issues, I think I would have started with a better set
Thanks Thomas. I like a challenge and the un cracked castings are hard to come by now
What is the Dulcich guide? Where can I find it?
