Typically the next step is a thinner head gasket for a tighter quench and higher compression. Then it's milling the head for desired cc's to increase compression. You may have to cut deeper valve reliefs depending upon how these motors are set up but that is easier than you might imagine. (Honestly don't know that part)
More than likely you really don't need a high compression piston unless your building a true race motor using racing level octane and or just really want a forged piston instead.

you can neither do a thinner headgasket, nor mill the heads for increased compression on these engines, given that they use a 1 piece front cover that goes from the oil pan to the heads
if you want compression you either make the combustion chambers smaller, or you do it through the piston
