Cometic's .056" MLS cylinder head gasket for Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 uses a 4.310" bore and multi-embossed stainless layers with Viton-coated faces. Engineered to seal modern high-output engines without sealants, it withstands differential material shearing and resists corrosion. The center shim can be tailored for thickness, helping distribute clamp load and reduce bore distortion for aftermarket head applications.
