The Cometic MLS cylinder head gasket for Chevrolet Mark-IV big block V8 is a .040" unit with a 4.500" bore and Brodix water passages. Built from multiple embossed stainless steel layers with Viton-coated outer faces, the gasket rebounds and resists corrosion while sealing aluminum and iron surfaces without sealants. The layered design reduces clamp load and evens load distribution for improved sealing.
