Compression Experts-What's precise compression stock LS6 heads & -2cc Diamond Pistons I am hoping that the compression ratio is 10:5 to 1 (don't ask me why I want so much compression that's my secret ) but using my bone stock LS6 heads and GM gaskets, what is the exact compression ration on a 347 cubic inch forged LS6 motor using -2cc Diamond Pistons.
Thank for your reply that answers this specific question!

Assuming a 64cc chamber, 2cc valve relief, .006" deck height, and .056" gasket, the compression is 10.35:1.
If the gasket is .052, then the compression is 10.45:1.
If the gasket is .052, then the compression is 10.45:1.
