Cometic MLS head gasket for Chevrolet Mark-IV Big Block V8, 4.630in bore with a compressed operating thickness of 0.053in. Comprised of multiple embossed stainless steel layers with AMP coatings and an uncoated center shim, the outer layers are coated with Viton on both sides (heat resistant to 250 C/482 F). The MLS construction seals without sealants, suits aluminum-to-aluminum or aluminum-to-iron combinations, and helps distribute sealing load while requiring less clamp load and reducing bore distortion.
