The Cometic MLS head gasket for Buick Big Block V8 with a 4.400 in bore and .030 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 withstand harsh sealing environments and heat to 250°C (482°F). An uncoated stainless shim allows thickness customization; MLS construction rebounds, resists corrosion and reduces clamp load to limit bore distortion.
