Pro-Comp's parts are all knock offs. It's junk! Everything made over seas. The only thing I found of their's to be ok were Valve Covers. Stay real far away from their electronics! I tried a while back selling some of their parts in my store. For every ten parts sold I would get back five for defects. Packed up all their stock and gave it back quick! Research back a few years, they lost a huge law suit with MSD because they were copying their electronic 6AL ignition boxes to the T from the outside but the guts were garbage. Now I see their sponsoring a drag car and I would bet their not using their own equipment and parts.

I used one of the proform chokeless main bodies on a holley 750 vaccum secondary and loved it!

hey Mike did you get the e-mails?

I got a set of Pro Comp BBC aluminum heads. Hoping to dyno this spring if my lawyer doesn't get all my money.

Are these supposed to be ok? Anyone try them?

Oh and P.S. don't give me a bunch of cr@p about silly gripes and diy screw ups. I have read reviews that sounded so silly they must have been totally made up or should stick to pipe wrenches.
I don't claim to be an expert but this aint my first rodeo.

procomp heads are fine, just do a good valve job on them, also add a bit of clearance to the guides... use good quality manley inconel exhaust valves... (nothing else compares) make sure your spring pressures are on the high end of spec, and use ARP studs or bolts... Cometic gaskets...
I am acredited race engine builder, and I use this product in certain budget concious builds... never had an issue because preparation is key to success in any build...

I got the 11/32 stem SS valves with the heads, should they do ok with a 496 stroker with double springs at 350 lbs seat press? This cam is hyd roller at .598 & .610 I understand to be like a basic Merc 500 cam. Do you think these valves are ok for this moderate build.

I have Felpro flattened wire gaskets, prob with those?
Also have the stud kit that Pro Comp sells for their heads, those ok for 600 or less HP?

Exactly, preparation is the difference between run or blow. I'm not in competition currently but spent time building, setting up and running drag engines with a dominate builder racer here.

I can see what his experience is. Thanks
