So I'm putting the head gaskets on with my stock E7s and I'm looking at my felpro gaskets that I ordered a while back and the cooling jacket ports are not present on the rear side of the gaskets. As you guys know there are water jacket ports on the rear and front of both the heads and block. I don't want to put them on and have something happen such as a stuck piston. So should I order new head gaskets or just lay the gaskets on top of each other in reverse and exacto knife provisions in the gaskets? The beast needs to run.... Summers here!
