The Cometic MLS head gasket for Buick Big Block V8 with a 4.400 in bore and .104 in nominal thickness is a multi-layer stainless steel cylinder gasket built to seal high-output engines without sealants. Embossed outer layers coated with Viton tolerate harsh sealing environments and heat to 250°C (482°F). The center uncoated stainless shim supports thickness variation; MLS construction rebounds, resists corrosion and requires less clamp load to limit bore distortion.
