Default quick compression question

if i was running 9:1 compression on a 6.0 with 74 cc heads, any idea what the compression would be with 64cc chambers?

Assuming you were running a .051" gasket to achieve the 9.1:1....with the same .051" gasket in there and 64cc chambers you'd be at 10.0:1 now.

Thanks for the answer Matt. I tried messing around with a compression calculator and didn't quite get it right. Thanks man. I am sure the OP appreciates it too.
