Ferrea Chevy/Chry/Ford SB 1.6in 11/32in 5.01in 14 Deg Flo Rad Grv +.100 Hollow Exh Valve - Set of 8

Ferrea is well-known for making high-performance valvetrain components, and this set of hollow exhaust valves is 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. Each valve measures 1.6 inches in head diameter and has a 5.01-inch overall length, with a 14-degree seat angle and a swirl-polished face for better airflow. The hollow stem design helps reduce weight, which can lead to improved valve float characteristics at higher RPMs.

This set includes eight valves, each featuring a +.100 inch stem height over standard, which can be useful for achieving correct installed height with certain cylinder head and camshaft combinations. The swirl-polished face is a notable detail that helps direct airflow smoothly into the combustion chamber, contributing to more efficient combustion. Ferrea uses strong materials to ensure these valves can withstand the heat and stress of continuous operation in performance applications.
