Cometic MLS cylinder head gasket for GM LSX Gen‑4 small block V8 (4.125in bore, right side) is built from multiple embossed stainless steel layers coated on the outside with Viton. The MLS construction provides strong sealing without sealants, copes with aluminum‑to‑aluminum and aluminum‑to‑iron interfaces, rebounds to resist corrosion and shear, and uses an uncoated center shim layer to accommodate variable thickness and help distribute load across the sealing area.
