Thread: pro comp heads any good ?

Tweet

I do have good news the oval intake ports line up perfectly fine and a valve job was done to them. had an old set of intake gaskets laying around they fit .. there is some meat for porting so that worry is out of the way. also I just got a set of the kb icon pistons with a 41cc dome on it so I guess little chamber heads are out of the question now haha.. I checked for valve clearance and we had close to 1/8 inch of clearance... is this a good thing or a bad thing?

well the rect ports do not line up . you do know there bbc open chamber head needs a 1017-1 fire ring of 4.530 or bigger like a 1057fire ring of4.630 looking a cc of 10.5 cc for the f1017-1 and 11.3cc for the f1057 so your Cr will take a hit you need to check this as the pro comp chamber is big and needs the big head gasket .gasket should not hang in the chamber of the head.icon ic9949 10.6 with 119 cc chamber it will be less then that is block zero deck. but no big deal less you want the CR
