Made by Payen this is the best head gasket to use for your Triumph TR6 1972 to 1976 from CC75001 and Triumph GT6 1972 to 1973. (These years of cars have the recess around each cylinder bore in the block.) Each gasket is a heavy duty Head gasket that is made with a perforated steel core, stainless steel fire rings and elastomer surface coating that heats very evenly. Another advantage of the coating is it is heat reactive for superior sealing over stock head gaskets and has extra red sealing beads (SAC track silicon bead) around problem areas to guard against weepage. No blown head gasket on your Triumph TR6 1972 to 1976 from CC75001 and Triumph GT6 1972 to 1973 with this head gasket.
