The Cometic MLS head gasket for GM LS Gen-3/4 small block V8 (4.130 in bore) is a multi-layer steel cylinder head gasket with a compressed operating thickness of 0.092 in. It seals modern high-output engines without additional sealants and suits aluminum-to-aluminum or aluminum-to-iron assemblies. This version uses HP shim technology to increase clamp load around the combustion chamber, while embossed stainless layers with Viton coating resist corrosion, rebound under load, and help reduce bore distortion by conforming load distribution.
