The Cometic MLS cylinder head gasket for GM Gen-V/VI Big Block V8 engines is a multi-layer stainless gasket designed for maximum sealing performance. This .066" compressed thickness and 4.540" bore fits high-output applications and installs without sealants. Embossed outer layers coated both sides with Viton resist heat to 250°C (482°F). The uncoated stainless shim layer allows thickness variation to match needs while improving clamp load distribution and limiting bore distortion.
