Cometic Chevy Mark-IV/GM Gen-V/VI BB V8 .030in. MLS Exh Hdr Gasket w/ AFR BBC Magnum 24 Degree Heads

Cometic Gasket has a reputation for making solid Multi-Layer Steel (MLS) gaskets, and this exhaust header gasket is no exception. It's designed to seal the gap between your exhaust headers and the cylinder head on Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines, especially those fitted with AFR BBC Magnum 24 Degree Heads. This gasket is built to handle the tough conditions found in exhaust systems, helping to keep those gases flowing where they should and preventing leaks.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel, which gives it strength and helps it resist corrosion and maintain its shape under heat. The outer layers are treated with a Viton rubber coating on both sides. Viton is known for its heat resistance, able to withstand temperatures up to 482°F, and it also helps create a reliable seal even on surfaces that aren't perfectly smooth. This gasket is also asbestos-free, offering a safer option for your build.

This particular gasket is sized at .030 inches thick, which is important for achieving the correct compression and sealing in your specific engine setup. It's a well-made part that fits a wide range of vehicles, including popular models like the Chevrolet Bel Air, Impala, and C10 Pickup, among many others. If you're working on a Big Block Chevy and need a dependable exhaust header gasket, this Cometic option is a solid choice.
