Stan Weiss has them listed as flowing 386cfm after porting from Modern Cylinder Head.

I bought a set and used all top of the line stuff. Had them CNC ported and they just didn't compare to my B1's or my old Indys. If you buy them be forewarned that NOTHING is helicoiled on these heads and be sure to clean out all bolt holes as some are filled with chips. The valve job from the factory sucks and mine had to be cut .100 because they were not flat. I also had problems with leaking at the valve cover rail. You also have to use gasketed spark plugs with them. My advice, if you have a small budget buy the Stealths from 440 source. If you can buy them the B1 originals or B1-BS's are hard to beat. I would rather have a set of 915's than ever deal with another set of ProComp pieces of crap.

I run a set on one of our 512 cars. I purchaced my set complete cnc std. port window. The heads make good power for "what they are". I don't think I'd do it again though. As stated above best bet would be to have a good head builder start on them from bare cores if you decide to use the pro comp. It took a fair amount of work to get mine corrected. It's a good design but Real Eddy Victors would be about the same price when all is said and done.

And you would be supporting a GREAT company.

No. The quality is much better, but they are made over seas also.

You should really update your thread on Mopar Style, this was your last post about your PC heads...

"I have ran mine on my digger and like them alot. Now they are not bottom of the barrel as they have all the good stuff on them. I went with Hughes valves, Hughes offset rockers, titanium retainers, K-motion springs, Comp locks and spring cups, heli-coiled the rocker stand and exhaust manifold holes, and opened them up to max wedge ports. All that said, you are going to spend a ton of money whether you go with these or Indy, Victor, etc. The casting is just that, a casting. It's what you put on them and what work you do to them that matters in the end. I actually gained E.T. over my Indy's for what it is worth."
