Unity Motorsports On the live show with you, David and UT, I saw John W comment to UT that David was looking for a junk 440 head. Would be neat to see what David can do with one or advice on porting one.
@@rong4189 I can tell you this years ago... DV ported a set for Steve Dulcich and it made over 660hp NA out of a 440... Not bad for a set of Stock Castings!!!
It’s a preference thing. Many guys will just hog everything everywhere. I don’t think that’s most effective. Hopefully my Porting keeps evolving and improving 🤞🏻
I got an '81 225 that I'm rebuilding on a tight budget. It will go in my '74 Dart and used as my daily. On my head I've blended the bowl's too the seats ending about half way down, streamlined the valve guide bosses (?) on the side facing the ports and rounded the rest off, and just broke the sharp edge of the short turn radiuses. Next I'm going to match the exhaust ports too the largest one and do the same on the intake side. After that, I'll smooth and polish the exhaust side (ports and bowls) and just clean up the intake side leaving a little roughness. On my intake (stock 1bbl) I'm going to match the ports too the largest as far as I can reach then do the same on the exhaust manifold (OEM). Once that's done, I'll do what I need for the exhaust manifold port to be a little larger the the exhaust port on the head and the do the opposite on the intake side. This is for helping reduce reversion. Only thing left will be milling the head for a 9.1:1 compression, I've already took the lip off the back of the valve. If money allows, I'll have a three angle valve job done. I know I ain't going to have a 1,000hp monster. I don't want that. Just wanting to pick up a little extra while it's apart to better suit modern times and make the driver experience a little better while maintaining good driving manners and be reliable for 500k or more. Side note: Since every time I find the Super Six intake and exhaust manifold it cost an arm and a leg, I'm going to make my 1bbl intake work for me. I need to get an adaptor to fit a modified Weber 38 (vacuum secondary) to my intake and I plan open up everything on the secondary side that I can for better flow and weld in a piece of metal in the adaptor coming out the bottom slightly to separate the unopened primary side to keep velocity up. Just going to match the adaptor to the intake plenum on the primary side. I think it should work great once done and dialed in how I want it.
I've found the guide bosses are that large due to core shift. On mine, one cylinder would be centered while another would be so far over it left about .040 on one side with a huge amount on the other. Best to sleeve with bronze and blend the rest out.
My main Set are some snap on bits that my dad left when he died. The long shank bit was a no name from Amazon for about 30$. It’s done well for me so far.
This set was about 6 hours total. I hit the wall of diminishing return. Although someday, I’ll do a perfect job on some big block heads(estimated 10-12 hours).
@@JustMoparJoe I always figured about 16 hrs for a pair of heads for me. Glad to see others home porting, I've just done is so much over the years I've lost my hankering for it. LOL.... But I enjoyed what you did !!!
I'm happy that I smoothed and opened the bowls a bit on those factory 302 casting heads I bought from Indy. They were cut for bigger valves, but still had a small throat. I wish I could put photos on here....I think it made a Helluva difference....you should've seen the slag in the exhaust bowls. I didn't measure anything...just opened 'em up until a 15/16 socket fell into the bowl (318willrun)...smoothed the transition to the roof. No science used, just great info from you guys! My engine runs great for ME....maybe not a race car, but suits my liking. 👍
I wish all the pro porters were as willing to share as DV, Darin Morgan has some good videos too. He just doesnt do many. Chad Speirs is talented but he shares nothing
The biggest flow problem isnt the pinch in the intake...... its the guide, the back cut on the valves, and the shrouding on both valves..... dodge is known for it..... cutting and tubing the pushrod boss does almost nothing surprisingly......
I agree. I’ve never tubed one. I did see on Instagram that Steve Dulcich just tubed some heads the other day for his 318 build. You are aligned with my research. I like the For A bodies only articles. Several on there with pictures and flow bench results. I can Monkey see, and Monkey Do.
The biggest increases will be cutting down the guide ends (dont leave any square edges), and deshrouding the valves..... the pinch point keeps velocity up......

You dun good Joe.I cringe when people talk about formulas,breaking thru installing sleeves and using epoxy.Seen epoxy fall out and grenade motors.Not for me.What you did will be a world of difference
I like these heads. Basically updated magnums. I’m sure trick flows and edelbrocks would outperform, but these had a better price point when I ordered. I think speedmasters have taken the Indy x place.
Thanks for asking! Most people don’t know about the common rule for compression. For every full point you raise/ lower, you change your hp by 3-4%(google it, it’s for real). So in a 400 hp engine, a full point would net you 12-16 horsepower. I’m my grinding, I may have lost .3-.5 of a point. But I gained increased airflow from the heads, which could easily counter act or even further offset the porting. Check out David Vizard’s videos. He shows his methods and usually tests on a 10/1 compression engine. I am increasing from a .048 to a .029 head gasket in this engine, which will make it better than its ever been!
I’m not that ballsy! Being a bracket car, I only want to run it 6-6,500. Cam range is 3,000-7,000, and I only have a 4.10 gear with a 28” slick. I may try the pushrod trick in some older heads I have.
@@JustMoparJoe @JustMoparJoe calm at first no one is brave ... hhaahaha but believe me the change is potentially drastic. I recommend you look for information on how to do intake port based on the work in CSA. Over there in the push rod section is where you have the minimum area and that is what determines the total RPM of the engine. The formula that You need to know is mcsa (minimun cross sectial área): bore*bore*stroke*RPM*0.00353/613.18 With this fórmula You can calculated how much area do you need For "X" RPM based in the CI of the engine. Now You need to measure the intake Port... Height * width less total área of corners (circule área of total long of corners) Well... I wish You the Best for You men i love You barracuda. I have the same combination in Demon but with a 280h cam. Sorry for my bad English... cheers from Venezuela

@@JustMoparJoe I found a cool set of aluminum w2 mild port and holley strip dom like 1400, head have had a repair nothing bad. Have. It seen many aluminum sets. Good looking out for the ford parts. Same here
Great video Joe, when you were grinding to deshroud the valves doesn't that make the combustion chamber a little larger thus lowering compression very slightly and does the increase in air flow worth the modification on closed chamber head like the one your doing! Is it just a small effect.
Vizard said do it. I know for every full point of compression, you gain 3-4% hp. We know the power is in the heads. I kind of followed his pattern in porting. I’ll definitely show the results 👍🏼
Good Job, Joe! I hope to have some Small Block Mopar heads on Vizards bench real soon!
Please share! I heard something about this 😉
I’ll look forward to watching the video too!

Never know until you try.
That’s it!

Great Video Joe! On average, how long does it take you to port a head?
This set took around 6 hours. Usually I think about 6-8 per head. These needed less because they were pretty open and already over ported on exhaust
I've found the guide bosses are that large due to core shift. On mine, one cylinder would be centered while another would be so far over it left about .040 on one side with a huge amount on the other. Best to sleeve with bronze and blend the rest out.
Excellent point! Thank you!
What brand bits are you using?
Are you happy with them?
My main Set are some snap on bits that my dad left when he died. The long shank bit was a no name from Amazon for about 30$. It’s done well for me so far.
Dumby valve
I keep them next to my Gumby valves
Stay with it !!!! I like to see people home porting !!!!!
Thank you! It’s enjoyable for me. I get caught in a time warp and never do as much as I’d like to.
@@JustMoparJoe how much time do you think it took you to work these over man? I’ve done this on several sets over the years

He’s an awesome resource! Thanks to Andy and John for introducing him to me. He’s a much older generation and has lots of knowledge to be taught!
Dude... Broke the push rod wall and make a new wall with epoxy... Easy fix and gain more cross sectial área... More CSA MORE HP AND MORE RPM
