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 0.045 in. It delivers strong sealing for high-output engines and installs without sealants for consistent performance. Constructed from embossed stainless steel layers with Viton-coated outer faces and an uncoated shim center, the gasket resists corrosion, rebounds under load, conforms sealing loads across the bore, and reduces required clamp load to limit distortion.
