The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .089 in nominal thickness is a multi-layer stainless steel cylinder gasket that seals high-output engines without sealants. Embossed outer layers coated with Viton resist harsh sealing environments and heat up to 250°C (482°F). An uncoated stainless shim layer enables thickness variation; the MLS construction rebounds, offers corrosion resistance and requires less clamp load to limit bore distortion.
