The Cometic MLS head gasket for GM LS1/LS2/LS3/LS6 Gen‑3/4 small‑block V8 engines (4.130" bore, 0.098" compressed thickness) uses multiple embossed stainless steel layers with Viton‑coated outer faces to deliver sealant‑free sealing for high‑output engines. It is suitable for aluminum heads to aluminum or cast‑iron blocks and resists material shear. A stainless center shim provides thickness control while embossed layers conform load distribution, reduce clamp load and limit bore distortion.
