The Cometic MLS cylinder head gasket for Chevrolet Mark‑IV Big Block V8 delivers multi-layer stainless steel construction with embossed, Viton-coated outer faces. At a compressed thickness of 0.086" and 4.320" bore, it seals high-output engines without sealants and resists corrosion and shear between aluminum and iron components. A stainless shim layer allows thickness control while reducing required clamp load and bore distortion.
