Default Head gasket question

I am having trouble finding a head gasket on the jegs or summit racing website for the 5.3 ls1. Would it be possible to use a head gasket made for a ls1 but with a bigger bore? I saw that they had one on summit racing for a bore of 3.910 and the 5.3 has a 3.780 bore, would this hurt my engine?? Thanks!

Lots of ls1s use the 6.0L gaskets. I dont see too much of a problem. It keeps the gasket away from the flame front, but it also lowers compression and adds a potential carbon buildup spot.

the cylinder bore is 4.000, not sure about the gasket. Probably around 4.020 or so
