possibly a noob question about LS1 heads on an LQ4...
This might be a straight up noob question, but I was looking on Summit's site looking for engine gasket sets and noticed a different part number for LS1 head gaskets and LS2 head gaskets, because of the bigger bore in the 6.0L blocks. Then it dawned on me, that I may have to get some machine work done on stock LS1 heads to fit on a 6.0 truck block? And what head gaskets will I need if I do put LS1 heads on a 6.0 truck LQ4?

No machine to put LS1 heads on a LQ4. I have 5.3 heads on my LQ4.

LS1 heads w/ stock gasket will yield 10:1 compression nearly stock LS1 (10.1:1).
Use a thinner gasket and mill them a bit to get 10.5-10.8:1
Use 5.3 heads w/ a .040 gasket and get 11.1:1
