The Cometic MLS head gasket for GM LS Gen-3/4 small block V8 (4.000 in bore) is a multi-layer steel cylinder head gasket with a compressed operating thickness of 0.092 in. It provides sealing for high-output engines without additional sealants and fits aluminum and cast-iron block pairings. Made from embossed stainless steel outer layers coated with Viton and an uncoated center shim, the gasket resists corrosion, rebounds under load, evens load distribution across the sealing face, and lowers required clamp load to help prevent bore distortion.
