The Cometic MLS head gasket for Buick Big Block V8 with a 4.312 in bore and .080 in nominal thickness is a multi-layer stainless steel cylinder gasket engineered to seal high-output engines without sealants. Embossed outer layers are coated with Viton to handle demanding sealing conditions and temperatures to 250°C (482°F). The center shim is uncoated stainless steel for tailored thickness, while MLS construction rebounds, resists corrosion and reduces clamp load and bore distortion.
