This listing is for a single Ferrea 5000 Series intake valve designed for Pontiac 400, 428, and 455 cubic inch engines. You get one intake valve with a 2.11-inch head diameter and a 5.213-inch overall length. This valve features an undercut stem design, which can help improve airflow around the valve guide.

Ferrea valves are known for their well-built construction. This particular valve is made from high-strength steel, chosen for its ability to withstand the heat and stress inside the combustion chamber. The undercut stem is a notable design detail that can contribute to better performance by reducing turbulence as the air-fuel mixture enters the cylinder. This is a single valve, intended for applications where only one intake valve needs replacement or for custom builds.
