2 base gaskets and a CR head gasket, .017" thick, should net around 205 psi.

Stock is 165.

to run the thinner head gasket do I have to pu the two base gaskets in first ?// I have the factory base gasket (not the original) in my quad i have a kit for the thin head gasket i was going to put it on just the head gasket not the two base gaskets. does this sound alright.
