I'm doing a 103 kit with HD 211 cams, HD race tuner and had the heads cleaned up with a 3 angle valve job. I stayed with HD stock flat top pistons and am considering the Cometic thinner head gaskets. The stock HD gasket is .40 and Cometic said I could go with a MLS .18 thick gasket. What would this raise my compresson to and is it safe and dependable ? Anyone done or heard of anyone doing this ? I don't want a race bike, just want to dust my Uncle.
