The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .070 in nominal thickness is a multi-layer stainless steel cylinder gasket that provides reliable sealing without sealants. Embossed outer layers coated with Viton withstand harsh sealing environments and heat up to 250°C (482°F). The uncoated stainless shim layer allows thickness customization; MLS construction rebounds, resists corrosion and requires less clamp load to limit bore distortion.
