Cometic's .045" MLS cylinder head gasket for Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 has a 4.570" bore and embossed stainless layers with Viton-coated faces. Suitable for Brodix-style aftermarket heads, it seals under high clamp loads and temperatures without sealants. The multi-layer assembly resists corrosion, rebounds under load and lets the center shim be varied to meet specific sealing demands and minimize distortion.
