With a 60cc chamber, you'll need a good-sized dish to be in the correct compression ratio range with pump gas.

With around a 16cc dish and the pistons about .010" in the hole, you'll be at around 9.5:1 SCR. With a .040" gasket and the pistons .010" in the hole, you'll have a .050" quench distance. That should be just fine, but if you're already having the block decked, you can have them square deck the block a little more and get the pistons optimally closer to zero deck.

I can offer some Keith Black hypereutectic pistons that would work great for a mild street engine like this, or for just a little more, Probe's FPS forged would be a nice piston that would allow some expansion later on if you choose.
