What makes this gasket better than a cork or paper one?

This Cometic gasket is made from molded rubber with a steel torque-limiting frame. This construction helps it seal better, resist blowing out from over-tightening, and handle higher vacuum levels than traditional cork or paper gaskets.

Does this gasket come with hardware?

This product is for the valve cover gasket only. You will need to reuse your existing valve cover bolts or source new ones separately.

How do I ensure a good seal when installing this gasket?

For the best seal, make sure both the valve cover and the cylinder head surface are clean and free of old gasket material, oil, and debris before installing the new gasket.

About this part

Product Details

If you're working on the valve covers of your classic Buick Big Block V8, getting a good seal is key to keeping oil in the engine and off your exhaust manifolds. This molded rubber valve cover gasket from Cometic is built to handle the job, offering a reliable seal for a range of Buick models from the late 60s through the mid-70s.

Unlike simpler cork or paper gaskets, this Cometic gasket uses a well-built molded rubber construction that's wrapped around a steel torque-limiting frame. This design helps prevent the gasket from blowing out or being damaged by over-tightening, and it can also handle significant vacuum. The .188 inch thickness is designed to fit specific applications, ensuring a proper seal without leaks.

This gasket is a solid option for anyone rebuilding or resealing the top end of their Buick V8. Make sure to clean your valve covers and cylinder heads thoroughly before installation for the best possible seal.
