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 0.054 in. It provides reliable sealing for high-output engines without the need for sealants and works with aluminum and cast-iron block combinations. Embossed stainless layers coated with Viton on the outer faces and an uncoated center shim resist corrosion, rebound under load, distribute load evenly across the sealing area, and help reduce clamp load and bore distortion.
