This Cometic MLS head gasket fits GM LSX Gen-4 small-block V8 left-hand side with a 4.125" bore and compressed thickness of 0.051". Constructed from multiple embossed stainless-steel layers with Viton-coated outer faces, it resists corrosion and rebounds to maintain a seal without sealants. MLS construction handles dissimilar head/block materials, requires less clamp load and reduces bore distortion for high-output applications.
