Cometic MLS head gasket for 1975–1987 Buick V6 (196/231/252) Stage I & II applications with a 3.86-inch bore and compressed operating thickness of 0.080 in. Multiple embossed stainless steel layers form the MLS assembly; outer faces are coated with Viton and the center shim is uncoated stainless. Requires no sealants, suits aluminum-to-aluminum or aluminum-to-iron joints, resists corrosion and spreads clamp load to limit bore distortion. Viton resists heat to 250°C (482°F) and AMP embossing improves sealing across varied surface finishes.
