The Cometic MLS head gasket for GM LS Gen-3/4 small block V8 (3.970 in bore) is a multi-layer steel cylinder head gasket with a compressed operating thickness of 0.075 in. It provides dependable sealing for high-output engines and installs without additional sealants for consistent combustion integrity. Constructed from embossed stainless steel layers with Viton-coated outer faces and an uncoated shim center, the gasket resists corrosion, rebounds under load, evens load across the sealing area, and reduces clamp load to limit bore distortion.
