Hi,

Does anyone have any experience on the Pro Comp aluminum heads? I'm considering purchasing a pair for a big block off of E-bay. Pros? Cons?

Thanks!

Chris! They make a lot of stuff wires heads fuel regulators and my friend Mike has bought aton of these parts from a well known e Bay emporium in the S.eastern part of our country. He bought a set of bbc heads that lasted 2 runs before they blew a hole in between cyls 3&5. He has sent most everything back and got replacements no problem ,sometimes the e bayer didnt even want the old parts back . What does that tell you. At first sight the stuff looks great but after you really start looking at it you come to find out you don,t like what you see. What about the work installing these parts. I know first hand i am the one who helps him install the stuff . Nothing worse than paying for the same real estate twice it becomes cost prohibitive fast. I have posted on this before and this subject has been beaten to death,on tc tc &tn.There are enough problems installing firstclass aftermarket parts and thats good stuff. Save a little more and buy name brand stuff remember YOU GET WHAT YOU PAY FOR. ALEX

Chinese counterfeit knock-off junk. Castings are light, guides and seats are all over the place, most folks have found that once you get everything corrected, you could have bought first-grade heads instead.
Pass on 'em!!!

They are cast and machined in China. You may or may not get a dimensionally correct example. Ask me about how the coolant got into the oil....

i agree with all of them --i have a set on my 468 --i have done alots of work to them and my motor makes alot of power--but i havent run it enough to prove anything yet--even there own pro comp stud gurdle wont fit on them-everything has been a pain with them-probably just gonna be another pair that will end up back on ebay after i have spent a fortune trying to straighten these out

You can sometimes find the edelbrock heads for $1500 on sale.

GM trusted the quality of them; they come on their crate motors.

Brodix and AFR are usually well over $2000.

Thanks guys,

You made it an easy decision to steer clear from them. The search continues!
