The Cometic MLS head gasket for GM LS1/LS2/LS3/LS6 Gen‑3/4 small‑block V8 engines (4.130" bore, 0.060" compressed thickness) uses multiple embossed stainless steel layers with Viton‑coated outer faces to seal high‑output engines without sealants. Suitable for aluminum heads on aluminum or cast‑iron blocks, it resists shear between dissimilar materials. A stainless center shim controls thickness while embossed layers distribute load, reduce required clamp force and limit bore distortion.
