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 0.070 in. It offers reliable sealing for high-output engines and installs without sealants for consistent combustion integrity. Constructed with embossed stainless steel layers coated in Viton on the outer faces and an uncoated center shim, the gasket rebounds under load, resists corrosion, conforms sealing loads, and requires less clamp load to reduce bore distortion.
