Want to tell us why he is what you say?? Further, WHAT does that have to do with him showing us a head casting? Did he steal it or something?...LOL. The head he is showing us, is what IT is; has nothing to do with him. The fellow making these videos is a thief and full of crap FYI.

True, but the vid where he sets himself on fire is pretty hilarious. Just asking, but would these heads support 530ish horse on a 408 without winding it to the sky?

I've gone 9.73 with Edelbrock heads with a 2.08 valve and stock pushrod location shifting around 6800 rpm in my duster. And these have more porting avalible if I am hearing right that the intake floor is poured solid. I won't be sonic checkng a set till I buy my own

I went 10.70's shifting at 6600 with stage 2 eddies from Hensley(275@600) with a flat tappet and 727 at 3400 pounds with a cast crank 416. I figured that was probably 530-550. Absolutely nothing fancy. Small TTI step headers, excellerator intake, 4150 carb.

Sounds interesting. I'm wanting to end up running 10:50's @2850#. Should be a piece of cake.

What you naysayers are not getting, and probably that's because you don't want to, the China supply line is very much like a Chinese restaurant. The list of options is endless.
So when the Promaxx head guy orders up a set of bare castings, he can order any alloy he wants. It might cost him $5.00 per head.
He may be able to make mods to the casting cores as well. Bryce Mulvey talked about that when he was blowing up Moparts about the Airwolf heads. It was pretty clear from what he said that they were cast by/for ProComp and he made some changes to the port shape.
When you talk about keeping work in the USA, fine. I can go along with that. I write that into every specification I produce. BUT, keep in mind that the casting is probably the cheapest part of the head. Handling, machine work, valve guide and seat supply and installation, springs, valves are added. Then there is advertising and making the boxes and shipping from the port to the machine facility.......get the picture?
I bet if Keith Black used a Chinese foundry he'd be able to triple his output. Whoever said it above has it right, it's hard to get any product, much less a quality product, from an American foundry. They're dirty, the work is hard, and there are many dangers. Thus, the number of foundries is dwindling and the good ones are overbooked. At the same time that it's hot, dirty work, the foundryman has to have experience because casting is more of an art than a science. So foundries can't just hire someone off the street. And, the good ones probably can't expand because of the Not In My Backyard factor.
Kudos to pittsburghracer for keeping an open mind.

Thanks and that was well written but I will go one step further. PA isn't the greenist state in he nation but the EPA really hit us hard in the specialty steel market. As a Millwright we used to make and pour our own babbit bearings for our equipment. I retired in 2010 but they stopped us from work like that yeas ago and you should have seen the junk we were forced to use. A local bronze shop was totally closed down

For me it could have been as easy as pushing buttons but I didnt know that... with a little help I understand it now.. much better
