Is there a set amount for this?
For every cc you flycut in stock pistons, you lose 0.X compression, and gain .XXX clearance?

Clearance is simple. If you cut .040 into the piston, you have .040 more clearance. If flycutting @ home, don't worry about CC's. Go by measurements. From what I have "heard", a stock piston can be safely cut .100 but I personally wouldn't go that far. Cut .060 out, should be PLENTY....
Not sure on the compression calculations...
