GASKETS

Edelbrock part #7247 Exhaust Gaskets are designed for 1967-76 Buick 400-455 V8 engines. These Exhaust Gaskets are made of EnCore HTX-900; a high-density non-asbestos fiber/metal core composite material consisting of two graphite coated, heat resistant fiber blended sheets that are mechanically and chemically fused to an expanded steel core. The finished product provides high heat resistance, excellent load retention and unmatched sealing performance on exhaust manifold and header applications. A 50% recovery rate allows for gasket expansion in the event your header loses the proper header bolt torque. Gaskets future a 1.20"x 1.63" port size.

When installing new headers, or putting them back on after working on your vehicle, it's important to use a new set of gaskets. Edelbrock exhaust gaskets are made of EnCore HTX-900--a high-density, non-asbestos, fiber/metal core composite material consisting of two graphite coated, heat-resistant, fiber-blended sheets that are mechanically and chemically fused to an expanded steel core. The finished product provides high heat resistance, excellent load retention, and unmatched sealing performance on exhaust manifolds and headers. A 50 percent recovery rate allows for gasket expansion in the event your header loses the proper header bolt torque. Edelbrock exhaust gaskets are the perfect choice.
