The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .072 in nominal thickness is a multi-layer stainless steel cylinder gasket engineered to seal high-output engines without sealants. Embossed outer layers coated in Viton cope with demanding sealing and temperature conditions to 250°C (482°F). The uncoated stainless shim allows thickness tuning; MLS construction rebounds, resists corrosion and reduces clamp load to minimize bore distortion.
