Cometic Chevy Mark-IV Big Block V8 .125in Fiber Intake Manifold Gasket Set - Brodix RR BB-O Heads

If you're working on a Chevrolet Mark IV Big Block V8 and need to seal your intake manifold, this gasket set from Cometic is a solid choice. It's specifically designed to work with Brodix RR BB-O heads and features a .125 inch thickness, which is important for achieving the right compression and seal in your engine build. This set fits a wide range of Chevrolet vehicles from the mid-60s through the late 70s and early 80s, including popular models like the Impala, C10 Pickup, and Camaro.

The gaskets are made from AFM material, which is a chemically blown synthetic rubber bonded to an aluminum core. This construction offers good temperature resistance, holding up well over 250°F, and it maintains its torque well over time. A notable benefit of this material is that it doesn't require any gasket sealers or re-torquing after installation, making your job a bit simpler. Cometic manufactures these to meet and exceed OEM quality standards, so you can be confident in their performance and durability for your engine.
