Cometic Mark-IV BB V8 .125in Fiber Valve Cover Gskt Set-Fits Brodix BP DN-9-9 Deg Valve Angle Heads

Cometic Gasket is known for making well-built sealing components, and these Mark-IV Big Block V8 valve cover gaskets are no exception. If you're working on a Chevrolet Mark-IV Big Block V8 engine, especially one fitted with Brodix BP DN-9 heads that have a 9-degree valve angle, these gaskets are designed to seal things up right. They're 0.125 inches thick, which is a common size that works well for many applications.

What sets these gaskets apart is their construction. Instead of just plain cork or paper, they use a soft rubber material wrapped around a steel torque-limiting frame. This combination is pretty smart because the steel frame prevents you from over-tightening the valve cover bolts, which can often lead to blown-out gaskets with lesser materials. It also helps them handle higher amounts of engine vacuum without issues, and they're built for extended reusability, meaning you might be able to reuse them if you ever need to pull the valve covers off again.

These gaskets fit a wide range of Chevrolet vehicles from the early 70s through the mid-80s, including models like the C10 Pickup, Impala, and Caprice, as well as many GMC trucks. They are specifically made for Brodix BP DN-9 heads with a 9-degree valve angle, so make sure that matches what you have before ordering.
