Is this a blown head gasket ?

My brother only uses Cometic head gaskets for the forumla racing engines he builds. He and recommend to put a small bead of high temp silicone around each of the water ports on the inner layers of the gasket and spray both sides of the gasket face with copper coat. Oh yeah, we’re talking about vintage high strung 10k RPM Cosworth DFV’s that were used in the 1970’s F1 cars... For a street motor they are over kill, a good ol Fel-Pro will be just fine...
