Ferrea Chevy/Chry/Ford SB 1.625in 11/32 5.56in 24 Deg S-Flo Rad Grv+.600 Hollow Exh Valve - Set of 8

This set includes eight Ferrea exhaust valves, each measuring 1.625 inches in head diameter with an 11/32-inch stem and a length of 5.56 inches. These valves are designed with a 24-degree seat angle and feature a radial groove for improved sealing, along with a hollow stem to reduce weight.

Ferrea is known for well-built engine components, and these valves are no exception. The hollow stem design is a notable feature that helps to decrease the overall mass of the valvetrain. This reduction in weight can lead to improved responsiveness and potentially allow for higher engine speeds. The radial groove on the valve face is an updated design element that aids in better gas flow and sealing against the valve seat, contributing to more efficient combustion.

These valves are a solid option for rebuilds on Chevy, Chrysler, and Ford small block engines. Ensure you confirm compatibility with your specific engine build and cylinder head requirements before installation.
