The Cometic MLS head gasket for GM LS1/LS2/LS3/LS6 Gen‑3/4 small‑block V8 engines (4.160" bore, 0.036" compressed thickness) combines embossed stainless steel layers and Viton‑coated outer faces to seal high‑output engines without sealants. It suits aluminum heads with aluminum or cast‑iron blocks and resists shear between materials. A stainless center shim manages thickness while embossed layers conform load distribution, lower clamp requirements and help prevent bore distortion.
