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 0.051 in. The MLS assembly uses embossed stainless layers with Viton-coated outer faces and an uncoated stainless center shim. No sealants are needed; the gasket suits aluminum-to-aluminum or aluminum-to-iron combinations, resists corrosion, and distributes clamp load to reduce bore distortion while AMP embossing enhances sealing across varied surface finishes.
