The Cometic MLS head gasket for Buick Big Block V8 with a 4.385 in bore and .120 in nominal thickness is a multi-layer stainless steel cylinder gasket that provides durable sealing without sealants. Embossed outer layers coated with Viton meet harsh sealing and temperature requirements up to 250°C (482°F). The center uncoated stainless shim supports thickness variation; MLS construction rebounds, resists corrosion and requires less clamp load to reduce bore distortion.
