Ferrea Chevy/Chry/Ford SB 1.6in 11/32in 4.96in 14 Deg S-Flo Rad Grv +.050 Hollow Exh Valve- Set of 8

Ferrea's F1024P hollow exhaust valves are built for Chevy, Chrysler, and Ford small block engines. These valves measure 1.6 inches in diameter with a 11/32 inch stem and a 4.96 inch overall length. They are designed with a 14-degree seat angle and feature a radial groove for improved gas flow, often referred to as S-Flo. This set includes 8 valves, each measuring 0.050 inches larger than standard size.

These valves are constructed with a hollow stem design, which helps to reduce overall weight. This weight reduction can lead to improved valve train stability at higher RPMs, allowing your engine to rev more freely. The material used is chosen for its durability under the high temperatures and stresses found in performance exhaust applications. The radial groove is a notable design feature that helps to break up exhaust gas flow, potentially improving scavenging and reducing exhaust port temperatures.

When rebuilding or upgrading the top end of your small block engine, these Ferrea valves are a solid option. They are designed to fit right into applications that require a larger valve size, specifically 0.050 inches over the stock dimension. Ensure you have the correct valve guides and spring pressures to match these performance valves for optimal engine operation.
