Cometic MLS head gasket for Chevrolet Mark-IV Big Block V8, 4.630in bore with a compressed operating thickness of 0.092in. Built from 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). MLS construction seals without sealants, suits aluminum-to-aluminum or aluminum-to-cast-iron assemblies, and promotes even load distribution while lowering clamp load to help limit bore distortion.
