Ls9 head gaskets?

Can Ls9 head gaskets be used on a turbo 5.3L? I've been reading alot of mixed opinions and i just wanna make sure i get a good head gasket that will hold up. thanks

That makes me nervous but it's been done multiple times.
4.8/5.3 3.910 vs a ls9 4.100 gasket bore

I use them and gone up to 14psi, others have done more. Some say that other stock MLS gaskets are better suited for the small bore of the 5.3L, LS1 gaskets come to mind.

Hell I've run stock gaskets to 22psi lol. Heads never even came off, just swapped bolts for studs one by one.
