Cometic copper head gasket for Triumph TR6 (1968–1971) is a .043-inch full dead‑soft copper gasket designed for 76mm bore, non‑recessed blocks. Copper material compresses during installation and is suited for engines machined for steel o‑rings and high cylinder pressures, requiring less clamp load. It conforms load distribution across the sealing area and is intended to seal without sealants or re‑torque.
