The Cometic MLS head gasket for GM LS Gen-3/4 small block V8 (4.100 in bore) is a multi-layer steel cylinder head gasket with a compressed operating thickness of 0.089 in. It provides a no-sealant sealing solution for high-output engines and suits aluminum and cast-iron block combinations. Embossed stainless steel outer layers coated with Viton and an uncoated shim center give corrosion resistance, rebound under load, even load distribution across the sealing face, and reduced clamp load to minimize bore distortion.
