Help figuring my CR

[Mrturner1]

I need a little help figuring out my compression ratio. I know most of the requirements for the calculator, but I'm missing a few still. I don't know piston stroke, or the number for factoring in piston valve relief CC into the equation. I have a stock 350 short block, 4 valve relief stock pistons .025 in the hole. It's a .040 over bore, and 67cc combustion chambers on the heads. And the head gasket thickness is .039 I think that's everything but let me know if I need more info.
