Compresstion question!!

I have built 346ci with 72cc Heads the compresstion is around 8:5.1 with stock sized head gasket now I'm thinking about going with 57cc heads from TSP with a thiner head gasket for 11+ compresstion is that possible???

Does anybody have any idea what my compresstion will be???

Thanks.

If you mean compression here are two online calculators that might help:

Are your pistons true flat-tops, or do they have valve relief or dish? If so, how many cc is the relief or dish? With a true flat-top like the OE piston, you'd have over 12:1 with a .040" and 57cc chamber!

I'm gonna hi-jack for a second.

Matt, I have one of your forged 347's with Diamond pistons. I have stock replacement Fel Pro head gaskets and a set of stock LS2 heads. What would my compression be?
