The Cometic MLS head gasket for Chevrolet ZL1 Mark-IV Big Block V8 (4.300" bore, nominal .040") combines multiple embossed stainless steel layers with Viton-coated outer faces to create a durable, corrosion-resistant seal. MLS construction tolerates aluminum-to-aluminum and aluminum-to-iron applications without additional sealants. The uncoated center shim layer can be varied to achieve the desired thickness and to distribute load across the sealing surface.
