The Cometic MLS head gasket for Chevrolet ZL1 Mark-IV Big Block V8 (4.250" bore, nominal .080") is built from multiple embossed stainless steel layers with a Viton coating on the outer faces. It seals high-output engines without sealants and tolerates mixed head/block materials while resisting corrosion. The layered core shim allows thickness variation to match sealing requirements and reduce clamp load and bore distortion.
