BBK GM Small Block Exhaust Header Gasket Set

When you're installing new headers on your GM small block engine, a good gasket is crucial for a leak-free seal. These BBK header gaskets are built with a steel-reinforced graphite material, often called 'Secure Seal' by the manufacturer. This construction helps them handle the heat and vibration common with exhaust systems, providing a solid seal that lasts. They're designed to work with most stock or aftermarket header applications, making them a popular choice for many builds.

The graphite material itself is known for its ability to conform to surfaces and withstand high temperatures, while the steel reinforcement adds strength and helps prevent blowouts. This combination means you can expect a more reliable seal compared to basic composite gaskets. The port size is 1 3/4 inches, which is a common size for many performance headers on 5.0L and 5.7L GM engines.

This set includes gaskets for a pair of headers, so you'll have what you need for both sides of your engine. If you're swapping headers or replacing old, leaky gaskets, this BBK set is a well-built option that aims for a long-lasting seal.
