Valve Clearance

I am doing a Hotcam kit, but my questions is am I going to run into problems with having 6-7 thousandths taken off the heads and using the Impala HG?

I think it's 1 cc for every .006" off the heads, so both that and the impy head gasket will bump your compression nicely.

I doubt you'll have PTV issues with that small cam.

yeah the head guy said .006 is .1 compression so that would be 10.6:1 and with the twenty thousands with the impy HG I sould be around 11.0:1
