pro comp heads - 02/03/12 10:26 PM
Are pro comp heads any good like to here your opinion

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.

are the 440 sauce a pro comp 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.
