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 0.120 in. It provides robust sealing for high-output engines without needing sealants and works for aluminum and iron block combinations. Made from embossed stainless steel layers with Viton-coated outer faces and an uncoated shim center, the gasket resists corrosion, rebounds under load, distributes sealing loads evenly, and requires less clamp load to reduce bore distortion.
