so what would my compression be on a 6.0 block with ls-1 heads? is that going to push up to 10:1 or more? i am force feeding my motor. will i need to get different heads or get the chambers milled?

The 5.7 heads will raise your compression and do not flow as good as the 6.0 aluminum heads. I would stay with the 6.0 heads if you have the aluminum ones. If not, try to find some. The lower compression will be better for you anyways.

Without running up the numbers, I'd say you'd be pretty close to 10:1. Not as good for boost.
