The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .051 in nominal thickness is a multi-layer stainless steel cylinder gasket engineered to seal high-output engines without sealants. Embossed outer layers use a Viton coating to withstand harsh sealing and temperatures up to 250°C (482°F). An uncoated stainless shim layer enables thickness adjustments; the MLS design rebounds, resists corrosion and reduces clamp load to help prevent bore distortion.
