Cometic MLS head gasket for Chevrolet Big Block V8 features multiple embossed stainless steel layers with outer Viton-coated faces and an uncoated stainless steel center shim layer, offering a compressed thickness of 0.060 inches. MLS construction provides strong sealing for aluminum-to-aluminum or aluminum-to-iron configurations, resists corrosion, and reduces required clamp load to minimize bore distortion. The embossed, coated outer layers improve sealability in demanding conditions.
