The Cometic MLS cylinder head gasket for GM Gen-V/VI Big Block V8 engines combines multiple embossed stainless layers for high-output sealing. This .036" compressed thickness with a 4.630" bore installs without sealants and suits demanding mating surfaces. Outer layers are Viton-coated on both sides for resistance to 250°C (482°F). The uncoated stainless shim layer can be varied for thickness needs, improving load distribution across the sealing area and reducing bore distortion.
