The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .056 in nominal thickness is a multi-layer stainless steel cylinder gasket that seals high-output engines without sealants. Embossed outer layers feature a Viton coating to tolerate harsh sealing conditions and temperatures up to 250°C (482°F). The uncoated stainless shim supports thickness variation; MLS design provides rebound, corrosion resistance and reduced clamp load to minimize bore distortion.
