So zero deck with that .041 gasket will work fine.

I've never heard of changing compression by cutting the pistons. I was thinking you'd cut in the center of the piston and make a dish so it wouldn't affect quench.

So they'd have to take it out of the combustion chamber to change the compression ratio? Again what tool would I use to measure that when changing it?

EDIT: I read around a bit more and a few engine builders recommend a quench of .050" for a safe bet. If I deck it down to 0.050" from 0.056" (0.041" gasket + 0.015" deck clearance), I'll get that quench, the deck can be cleaned up with a .006" cut, and I only need to take out 2cc of each chamber for a 9.0:1 CR or 6cc for 8.65:1. Or anywhere in between.
