While the Fel-Pro gaskets are very good materials, there head gasket surrplied in there kits are .039 thick and a bore of 4.1+ I think it is. Alittle thick and wide. But not a huge end all deal. These are the gaskets in the MP gasket kit now.
I have been reading some poeple have problems finding the MP OE head gasket. They are .028 compressed thickness. This is the one I would use with the combo.
IF you can find a head gasket closer to the diamentions of the 318's bore and as thinn as possible, that would be ideal.
