i have a 250r with a stock bore piston (virgin cylinder). the aftermarket gasket kit i got had a head gasket that was .010" thick. the stock one i took off was .060" thick and had 2 extra water holes cut into it on the exhaust side while the aftermarket only had 1. I put a stock head gasket on, and compression is 165psi. What would it have been with the .010 gasket? enough to notice at all? would those 2 extra 1/4" holes that the aftermarket gasket was missing caused too much heat ?
thanks
