Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.375in bore and .098in compressed thickness. Multiple stainless steel layers and embossed outer surfaces coated in Viton form a corrosion-resistant, high-strength seal that requires no sealants and tolerates dissimilar head/block materials. The uncoated center shim can be varied for specific thickness needs, while embossed layers conform to finish and distribute clamp load more evenly.
