I think if you have to ask that question, you should probably pay somebody to build the engine for you.

lol. ok sure.

i would say i know a lot about the LS. i just didnt know if there was a "common" rule about head gasket only so much bigger than bore.

Bigger bore gasket wont hurt anything except increase the combustion chamber size a hair, lowering compression....then again why would one do this anyway? The opposite though... having a too small of a gasket would allow the fire ring to be exposed inside the chamber and get burned up or not compress and seal right.
