The Cometic MLS head gasket for GM LS Gen-3/4 small block V8 (4.160 in bore) is a multi-layer steel cylinder head gasket with a compressed operating thickness of 0.089 in. It provides a no-sealant solution for sealing high-output engines in aluminum or iron combinations. Featuring HP shim technology to boost clamp around the combustion chamber, the gasket pairs embossed stainless layers and Viton-coated outer surfaces with an uncoated shim center to resist corrosion, rebound under load, and reduce bore distortion.
