    I also run skimmed standard pistons, mine were skimmed to the bottom of the squish area theoretically making them flat top with the exception of the valve cut outs.

    My compression ratio is now 8.5:1

    I personally don't like the two head gasket approach but each to their own.

    Just my 2ppp

          I`m also running 500+hp with standard pistons and scat rods.

          The approach i took was to keep the standard squish area in front of the inlet valves but make the eccentric dish wider and deeper. This made the crown 0.5mm thinner and gave me a CR of 8.46 with the standard head gasget.

          Have a look.
