The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .074 in nominal thickness is a multi-layer stainless steel cylinder gasket made to seal high-output engines without sealants. Embossed outer layers are Viton-coated to handle harsh sealing environments and temperatures to 250°C (482°F). The center shim is uncoated stainless steel for thickness options; MLS design rebounds, resists corrosion and lowers clamp load to reduce bore distortion.
