Re: Lowering CR, Has anyone tried...
Have not tried it, you can remove enough material to get to 15-16:1 without changing the swirl characteristics of the bowl.
CC's removed from the bowl to get to 15:1 or 16:1 will change depending on your quench distance, head gasket kit used, valve recession and relief work, it will be between 8-12cc which is why you need to measure all the other variables before cutting the pistons, or stick to a known combination.
