Cometic Brodix Chevrolet Big Duke / Brodie 4.63in Bore .060in MLS Head Gasket

When you're rebuilding the top end of a big block Chevrolet engine, especially one fitted with Brodix Big Duke or Brodie heads, getting the seal right is critical. This Cometic Multi-Layer Steel (MLS) head gasket is built to handle the pressures of high-output applications. It's designed to provide a solid seal without needing any extra sealants, making the job cleaner and more reliable.

This gasket is constructed from multiple layers of stainless steel, which gives it strength and the ability to rebound, helping it resist corrosion and maintain its seal over time. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. The center layer is stainless steel and can be varied in thickness; in this case, it's set to a compressed thickness of 0.060 inches. The water ports are intentionally undersized, allowing for customization during installation with aftermarket heads. This gasket fits a wide range of Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines, including models like the 1965-1975 Chevrolet Bel Air, 1968-1986 Chevrolet C20 Suburban, and 1965-1976 Chevrolet Impala.
