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 0.056 in. It seals modern high-output engines without needing sealants, suitable for aluminum-to-aluminum and aluminum-to-iron assemblies. Embossed stainless layers with Viton coating and an uncoated shim center provide corrosion resistance, rebound under load, improved load distribution across the sealing area, and reduced clamp load to help prevent bore distortion.
