LS1 3.910 bore head gaskets on LS2 heads? Am I going to have a problem running an LS1 3.910 bore GM MLS gasket on an LS2 head? Will the chamber on the head be larger than the bore of the gasket?

As in a 243 casting? If so then no you shouldn't have an issue, as long as we're talking about a LS1 bottom end. The 243 casting is what was used in the LS2s and LS6s with the only difference being the valves used, chambers are the same size.
