The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .040 in nominal thickness is a multi-layer stainless steel cylinder gasket that delivers dependable sealing for high-output engines without sealants. Embossed outer layers are Viton-coated to meet demanding sealing and temperature needs up to 250°C (482°F). An uncoated stainless shim allows thickness customization; the MLS design rebounds, resists corrosion and reduces clamp load and bore distortion.
