Cometic MLS cylinder head gasket for GM LSX Gen‑4 small block V8 (4.125in bore, right side) features multiple embossed stainless steel layers coated with Viton and a compressed operating thickness of 0.098". MLS construction seals effectively without sealants, tolerates aluminum‑to‑aluminum or aluminum‑to‑iron pairings, rebounds to resist corrosion and shear, and uses an uncoated center shim layer to adjust thickness and improve load distribution across the sealing area.
