The Cometic MLS head gasket for Buick Big Block V8 with a 4.400 in bore and .080 in nominal thickness is a multi-layer stainless steel cylinder gasket designed to seal high-output engines without sealants. Embossed outer layers use a Viton coating to tolerate harsh sealing environments and heat up to 250°C (482°F). The center uncoated stainless shim accommodates thickness variation; MLS construction rebounds, resists corrosion and reduces clamp load to limit bore distortion.
