Getting my setup all ready for a GT40 3 bar explorer head swap. Looking at a Felpro gasket set for the 93 Cobra. I am running the 93 cobra intake. Will the head gaskets work with the larger 1/2" bolt holes? (Don't 93 gt40's have 7/16 bolts?) Reusing my stock bolts, so will be the smaller 7/16" bolts compared to the 1/2" head holes.
