Head Gasket - HELP
What head gasket for my .020 over 4G63 motor??? I have people telling me I would be okay with a stock size head gasket, yet companies like cometic make head gaskets to fit the bore size. Even though it is only .5mm... how much difference could it make? Harmful to use stock size on .020 over motor? I was also informed that it would affect my compression ratio possibly using a stock sized one on my .020 over motor.
