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 0.027 in. The MLS construction uses multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless center shim. No sealants are required; the design suits aluminum-to-aluminum or aluminum-to-iron joints, resists corrosion, and distributes clamp load to minimize bore distortion while AMP embossing enhances sealing.
