Re: 6.0 Liter heads on 5.3 Liter
Compression is going to be 8.6:1 using a stock LQ4 head and gasket. A better choice IMO is a stock chambered LS1 head and gasket for a CR of 8.9:1. If you have any chamber work done to them, the CR will be lower. This is assuming you are working with a stock 5.3 short block.
One other option - LS1 heads with a thicker LS1 head gasket (Cometic makes one @ .080 I think). This will put you @ 8.45:1. Its just begging for more boost.
