Cometic MLS cylinder head gasket for Chevrolet Mark-IV big block V8, 4.350" bore and .060" thickness. Built from multiple embossed AMP-coated and uncoated stainless steel layers, this gasket uses HP shim technology to boost clamp load around the combustion chamber for better sealing on open-deck blocks. Embossed outer layers coated with Viton improve sealing in harsh flange and surface conditions while helping conform load across the sealing area.
