Header Gasket Set - BBF 429/460 Retangle Port

The MAHLE ORIGINAL Header Gasket Set - BBF 429/460 Rectangle Port is designed specifically for Big Block Ford engine applications requiring precision exhaust manifold gaskets. This gasket set is ideal for those undertaking engine rebuilds or restorations, ensuring a reliable seal for optimal performance.

Featuring a steel core graphite construction, these gaskets are rated for 2.020 x 2.070-inch rectangle ports. The design maintains consistent compression across thermal cycling and high-heat engine operation, providing structural integrity under extreme temperature fluctuations. The graphite facing material ensures reliable sealing without galling or binding at the manifold interface.

This gasket set is sold as a pair, covering both driver and passenger-side headers for a complete seal package. Proper gasket selection is crucial to prevent exhaust leaks that can compromise performance and allow uncontrolled oxygen ingress into the combustion chamber. MAHLE ORIGINAL gaskets maintain the precise port geometry needed for uninterrupted flow and sealed operation.
