The Cometic MLS head gasket for GM LS1/LS2/LS3/LS6 Gen‑3/4 small‑block V8 engines (4.190" bore, 0.030" compressed thickness) features multiple embossed stainless steel layers with Viton‑coated outer faces to provide sealant‑free sealing for high‑output applications. It supports aluminum heads on aluminum or cast‑iron blocks and withstands shear between dissimilar materials. A stainless center shim manages thickness while embossed layers distribute load, lower clamp requirements and limit bore distortion.
