Ferrea Chevy/Chry/Ford SB 1.625in 11/32 5.16in 24 Deg S-Flo Rad Grv +.250 Hollow Exh Valve- Set of 8

Ferrea is well-known for making high-performance valvetrain components, and these hollow exhaust valves are a prime example of their work. Designed for Chevy, Chrysler, and Ford small-block engines, these valves are built to handle the demands of performance builds. They feature a 1.625-inch head diameter and a 5.16-inch overall length, with a 24-degree swirl-flow radius groove for improved airflow.

What sets these valves apart is their hollow stem construction, which significantly reduces weight compared to solid valves. This lower mass means less stress on the valvetrain, allowing for higher RPMs and improved responsiveness. The valves are also +.250 inches longer than standard, which can be beneficial for certain cylinder head porting or camshaft profiles. They are sold as a set of 8, making them ideal for a complete V8 engine rebuild.
