Ferrea Ford 4.6L/5.4L 24V 1.553in 4.58in 21 Deg Flo O/S Sgl Grv S-Alloy Exhaust Valve - Set of 8

These Ferrea exhaust valves are built from S-Alloy, a material chosen for its strength and heat resistance, making them a solid choice for your Ford 4.6L or 5.4L 24-valve engine rebuild. With a 1.553-inch face diameter and a 4.58-inch overall length, these valves are designed to fit specific applications where improved airflow and durability are key.

The 'Flo' design and 21-degree seat angle are intended to help improve gas flow out of the cylinder, which can contribute to better engine performance. The single groove stem design is also a notable feature, often used to ensure proper valve seating and retention. This set includes eight valves, enough for a complete cylinder head replacement on a V8 engine.

When rebuilding the top end of your engine, using well-built components like these Ferrea valves can make a difference in the longevity and performance of your build. Ensure you have the correct valve seals and guides for your specific application to complete the installation properly.
