429-460 Ford Exhaust Gsk EXCEPT 429CJ & SCJ.68-78

The 429-460 Ford Exhaust Gasket (except 429CJ & SCJ) is a critical engine seal designed for big-block Ford applications spanning the 1968–1978 model years. As a mechanic rebuilding or servicing classic Ford performance engines, you know that a failed exhaust manifold gasket compromises both performance and reliability, allowing unburned gases to escape before reaching the catalytic converter and creating vacuum leaks that rob horsepower. FEL-PRO's engineered design ensures a lasting seal between your cylinder head and manifold, preventing heat loss and maintaining proper exhaust scavenging—essential for keeping those legendary 429 and 460 cubic-inch mills running strong.

This gasket is manufactured to OEM specifications using FEL-PRO's proven fiber-composite material, engineered to withstand the extreme thermal cycling and pressure fluctuations inherent to big-block exhaust manifolds operating at sustained high RPM. The gasket's lightweight construction—just 0.27 lbs—minimizes vibration transfer while maintaining structural integrity across all mounting points. Its compact profile (21.95 inches long by 3.9 inches wide) fits precisely within the exhaust port surface geometry, ensuring uniform compression and eliminating hot-spot leakage that can degrade performance and fuel economy.

This gasket is ideal for restorers, street-rod builders, and enthusiasts performing a complete engine gasket set replacement on 429 and 460 big-block Fords from 1968 through 1978. The exclusion of 429CJ and 429SCJ variants reflects their unique manifold geometry, so verify your engine code before ordering. Installation requires standard manifold bolt torque specifications and a clean surface preparation—a straightforward job that yields immediate benefits in throttle response, idle quality, and overall engine reliability. Stock this gasket for your next big-block rebuild or keep it on hand for emergency exhaust repairs.
