Cometic MLS cylinder head gasket for Buick 3800 Series II/III V6 (3.840in bore, right side) uses multiple embossed stainless steel layers coated with Viton and a compressed operating thickness of 0.120". MLS construction provides strong sealing without sealants, copes with aluminum‑to‑aluminum and aluminum‑to‑iron interfaces, resists corrosion and shear, and features an uncoated shim layer to manage thickness variations and distribute clamp load across the sealing surface.
