shadowsniper3006 Posted August 1, 2008 Report Share Posted August 1, 2008 can anyone figure out, or know how i can figure out how much valve to piston clearance i will have with stock heads decked to 64cc. I think thats around .040 of decking if i remember right its about .005 per cc. I called comp cams and they couldn't tell me. My cam is .610, .588 open close Int. 3 btdc 41 abdc Exh 51 bbdc 3- atdc would there be any problems decking the heads that much, like bolt holes lining up or ports not matching on the intake. I'm also thinking about using a .040 head gasket with this as well. Thanks Much! Brad Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted August 1, 2008 Report Share Posted August 1, 2008 the best and most accurate way is to clay the head. is that gasket .040" compressed? Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted August 1, 2008 Author Report Share Posted August 1, 2008 no, i was thinking of using the cometic .040, 4.030 gasket. I'm trying to raise the compression the easiest way i can think of. Quote Link to comment Share on other sites More sharing options...

shadowsniper3006 Posted August 1, 2008 Author Report Share Posted August 1, 2008 I think the lobes are HR Intalled at 109 int center line, ground +4 Quote Link to comment Share on other sites More sharing options...
misterp Posted August 1, 2008 Report Share Posted August 1, 2008 the best and most accurate way is to clay the head. is that gasket .040" compressed? Cleaner method - Bring the piston to TDC, and install head completely torqued to final spec. Remove the valve springs from the valves, they will fall into the chamber until the head contacts the piston, measure this distance with a dial indicator. Mr. P.
