The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .053 in nominal thickness is a multi-layer stainless steel cylinder gasket built for sealing high-output engines without sealants. Embossed outer layers are coated with Viton to handle demanding sealing environments and heat to 250°C (482°F). The center is an uncoated stainless shim for thickness options; MLS construction rebounds, resists corrosion and lowers clamp load to reduce bore distortion.
