The Cometic MLS head gasket for GM LS1/LS2/LS3/LS6 Gen‑3/4 small‑block V8 engines (4.190" bore, 0.051" compressed thickness) combines embossed stainless steel layers and Viton‑coated outer faces to provide sealant‑free sealing for high‑output applications. It accommodates aluminum heads on aluminum or cast‑iron blocks and resists shear forces between materials. The uncoated stainless center shim allows thickness variation while embossed layers conform load distribution and reduce bore distortion.
