PRO COMP ALUMINUM HEADS

DID ANYONE KNOW ANYTHING ABT THESE PRO COMP ALUMINUM HEAD. I SEE THEM ALL OVER EBAY AND I WAS WONDERING IF ANYONE HAD USED THEM AND IF THEY ARE ANY GOOD. I ONLY HEARD ON 1 GUY THAT USED THEM AND HE HAD WORLD PRODUCT HEADS ON HIS MOTOR THAT RAN 11.42 IN THE 1/4 AND THEN PUT ON THE PRO COMP ALUMINUM HEADS AND WENT 11.77 IN THE 1/4. JUST WONDERING IF ANYONE ELSE EXPERIENCED A PROBLEM LIKE THAT

ALRIGHT THANKS FOR THE HELP I WILL CHECK IT OUT

We just put a set on a 408 and had nothing but problems. Thought we had head gasket issues and come to find out it was a bad casting in the water jacket. After having this problem and doing some researech on them. There was a comment that if there was not a market for CHEAP parts we would not be in bussiness. That should tell you something. We are trying to get pro comp to help with this issue and will post later on the out come.

like he said, search the tech board, i havent heard one good thing about them, and many many bad things, terrible quality, junk basically.

I have a 424W going together right now using Pro Comp 210's. So far, everything looks real good on my set. I had the matching Comp Cams valve springs to my cam installed and the machine shop didn't see any problems. Hopefully we can get it to the dyno next week. I'll let you know how it goes!

Just my 2cents . . . . . .

I have been running a set of 210's for a couple of years now with no problems. I did have some initial problems with the pushrod tube holes, but once I machined them out and installed 1.7 ratio rockers, all was fine.

I used bare ProComp heads and added good valves, springs, retainers, keepers, studs and guide plates. That is the best way to get them to work properly.

About the only thing that is still screwy with mine is that it is nearly impossible to get the valve cover gasket to seal 100%. I have had the best luck with doubling up cork gaskets.

I made close to 80 drag passes this year, plus 2000 street miles without an issue. I have a .600 solid lift cam that requires 450 lbs open on the springs and I have spun the motor up to 6500 numerous times. Best time was 11.72@116.92.

I would never recommend the ProComp heads to anyone. Although they seem like a deal and can be made to work, there are certainly better choices of heads available.

I think I have outgrown mine and am going to do an upgrade. I recently traded for some 205 AFR's and will hopefully will be able to do a valid performance comparison.
