at 16 i ported a set of J heads on my 79 360 engine and put a set of used long tub heads on my 79 step-side. i was surprised in the change even with a stock cam. of course, when i got older and cars became a money pit lol i ended up stroking that engine. i even round off the intake, most people forget the intake.
Impressive flow numbers for a 1.92 valve size! I've heard it said before that Mopar small block heads have the ability to show more improvement than a Ford or Chevrolet small block head.
One of the advantages of doing your head to port match is that any fuel that has stuck to the port wall gets sheared off and pulled back into the air stream by the turbulence. Being relatively close to the valve I think that this is actually a significant advantage, particularly at part throttle operation. Regards Greg
Its not about "helping reversion" though, because the port always flows backwards first and for the same reason limits the mach speed no matter how small the ports we make. -juhana
I have a question about the EQ Chinese made heads. I used a set of EQ heads a long time ago when they were made in Aussie land and they worked quite well and had quality work. They were in a 98 Dodge 1500 pick up that I did some light towing with. Question on the Chinese units: are they cast & machined in China or machined elsewhere? I'm concerned about their durability more than performance, I would use them for light to medium towing. I know you do mostly performance work but you may have some input about their utility use. Still following the 318 mission impossible thing.
I did a set of Chinese vortecs not too long ago. Have a bunch of videos on them. The guides and seats were not great but they seldom are. The castings needed lots of work. Thanks
No way. They are all smoothing the parts. It’s a great feature using the very best whits all pulling together so Tony can go calling out Hemis at the strip one by one with a bone stock appearing ringer. What great fun! Eventually raffled to benefit St. Judes.

I think you have exceeded your question limit. Look back in my videos for an IOP program of a cylinder head. I could be convinced to do a iop work up on these. Thanks
IMHO, going from 1.92" to 2.02" will gain NOTHING in a truck and not worth the time or money. Even going from 1.92" to 2.08" on a truck, not worth the time or money. But the customer pays talk them into 2.08".

Great work sir 👍
Thanks!
Nice work Charles.
Picked up nicely.
Thanks for sharing. 👍
You are welcome.
It's gonna rock and roll. Especially if it's a roller cam. Put that N.O.S. on it ,somebody in trouble.
You make a very good point. Thanks
Like the exhaust final finish ..looked great
I can see I missed a few spots. Thanks

Nice, thanks.
Great work, sir!
Thanks
Pretty makes it fast goes right along with if it don't go chrome it.
I love it. Thanks
If you listen close you can hear the ocean in the port 🤘😆
That is natural convection air currents flowing through those ports!
Nice work.
Thanks!
I'd like to see the top of the pushrod pinch opened a little on the cracked head.
Great work
Thanks!

@@juhanahuovinen Are you sure Mr. Smarty pants?

Would you show how you add the dye to the assembly to get the patterns
I just need to remember to do it. Thanks

@@servediocylinderheads Kinda what I was expecting, thanks for the reply. Too bad they don't make them in Australia anymore.
I am very interested in the RPM intake manifold results, did you fully port that? or would another Intake like the Victor Jr work.
Fully ported with very rough texture. Stay tuned for full report. Thanks
Is this for just mopar joes ram charger?
No
Now we need to find out just how much better they are than the current magnum heads everyone sells. How much performance are we really losing ?
When I get some time I have a stock cracked Magnum. Thanks
Just started watching, your awesome! Any chance you have done Pontiac RA heads ? I’ve learned a lot so far.
30 years ago, Poncho stuff runs if done right. Thanks
I think a lite touch in the roof and it's peaked
Not sure what you mean?
Is the mission impossible project dead Charlie?
No way.

As far as I know it is still on.

Nice tow truck engine. Funny
400hp rear or crank?
Good question, I assumed crank but you are right. I will need to ask.
@@servediocylinderheads Also what compression ratio and fuel type? I can email you a build spec
@@brokentoolgarage I sent him a message about the combo. Stay tuned.
If its crank, heck, a small cam will knockit out of the park.
@@Robs-Garage-experiments Kinda the point, heavy, stock stall, 28" tires, 4400lbs, 3.55 gears. Small cam is the only choice!
Looks like some bad plug flooding mayb
I doubt it, dykem is way thicker so it clumps up. If you can spread the dykem fuel will really spead out. Thanks

In a Chevy or Ford the big valve would boost up the midrange flows quite a bit. I would think the same would happen on the Mopar heads. Thanks
Without further work no , with more work around valve unshrouding yes it will.
In that case, see about putting 2.08" valves in.
If you're goina go big, go big. Cut is about the same time wise.
