Cometic MLS head gasket for 1975–1987 Buick V6 (196/231/252) Stage I & II applications with a 4.02-inch bore and compressed operating thickness of 0.030 in. Multiple embossed stainless layers create the MLS assembly; outer faces are Viton-coated while the center shim remains uncoated stainless. The gasket needs no sealants, handles aluminum-to-aluminum or aluminum-to-iron mating surfaces, resists corrosion, and evens clamp load to reduce bore distortion. Viton stands up to 250°C (482°F).
