Copperseal Exh Gasket 429-460 Ford

The Copperseal Exh Gasket 429-460 Ford by Mr. Gasket is specifically designed for big-block Ford engine builders and restoration enthusiasts working with 429 and 460 cubic-inch powerplants. Exhaust gaskets are essential components that prevent exhaust gases, coolant, and oil from leaking at the junction between the cylinder head and exhaust manifold, a high-pressure, high-temperature interface that requires reliable gasket integrity.

Mr. Gasket's Copperseal design features a copper core construction that provides superior heat dissipation and conformability compared to standard steel gaskets. The gasket's thickness and material composition allow it to compress and conform to minor imperfections in mating surfaces, creating a tight, long-lasting seal even on older or freshly ported cylinder heads where surface finish may vary slightly.

Mechanics and engine builders restoring big-block Fords—from truck engines to performance builds—rely on this gasket for both OEM-specification replacements and modified applications. It is compatible with the 429 FE and 460 FE engine families commonly found in 1970s Ford trucks, ensuring a reliable seal for these powerful engines.
