Cometic MLS head gasket for Chevrolet Mark-IV Big Block V8, 4.630in bore with a compressed operating thickness of 0.032in. Comprised of multiple embossed stainless steel layers with AMP coatings and an uncoated shim layer, the outer faces are coated with Viton on both sides (heat resistant to 250 C/482 F). The MLS design seals reliably without sealants, works for aluminum-to-aluminum or aluminum-to-cast-iron assemblies, and helps conform load distribution while reducing clamp load and bore distortion.
