The Cometic MLS head gasket for Buick Big Block V8 with a 4.400 in bore and .066 in nominal thickness is a multi-layer stainless steel cylinder gasket engineered to seal high-output engines without sealants. Embossed outer layers coated with Viton handle demanding sealing environments and heat up to 250°C (482°F). An uncoated stainless shim allows thickness variation; MLS construction rebounds, resists corrosion and reduces clamp load to help prevent bore distortion.
