Cometic Brodix Chevrolet Big Duke / Brodie 4.63in Bore .051in MLS Head Gasket

What you get here is a Cometic Multi-Layer Steel (MLS) head gasket, specifically made for Brodix Big Duke or Brodie heads on Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines. This gasket is built with multiple layers of stainless steel, giving it a strong rebound and resistance to corrosion, which is crucial for keeping a good seal under high output conditions. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal against the block and head materials, whether you're working with aluminum or cast iron.

The compressed thickness on this gasket is 0.051 inches, and it features a 4.630-inch bore. It's designed to work with aftermarket heads and includes undersized water ports, which gives you flexibility for custom porting during your build. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process. This type of gasket is a solid choice for engines that are pushed hard, offering improved sealing performance compared to older gasket designs.
