Cant answer your question directly, but do a search for Big Boyz Head Porting. They have an Evo compression calculator where you can add cam type, head gasket thickness, altitude, etc.
Not changing anything on the calculator (stock Evo 80 settings) and using a 0 altitude and a 0 deck height shows a cold cranking compression around 166 psi.
