The Cometic MLS head gasket for GM LS Gen-3/4 small block V8 (3.910 in bore) is a multi-layer steel cylinder head gasket with a compressed operating thickness of 0.084 in. It seals high-output engines without additional sealants and fits both aluminum and cast-iron block pairings. Made from embossed stainless steel layers with Viton-coated outer faces and an uncoated shim center, the gasket resists corrosion, rebounds under load, distributes sealing load evenly, and reduces required clamp load to limit bore distortion.
