This .060" Cometic MLS cylinder head gasket is built for Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 applications with a 4.310" bore. Multiple embossed stainless layers with Viton-coated outer faces offer sealing without sealants, capable of handling high cylinder pressures and mixed-material interfaces. The design rebounds under load, resists corrosion and allows thickness variation via the center shim for accurate fitment and durability.
