Ferrea Chevy/Chry/Ford SB 1.625in 5/16in 5.06in 24 Deg Flo Rad Grv +.150 Hollow Exh Valve - Set of 8

This set includes eight Ferrea hollow exhaust valves, designed for Chevy, Chrysler, and Ford small-block engines. Each valve measures 1.625 inches in diameter with a 5/16 inch stem and a total length of 5.06 inches. They feature a 24-degree face angle and a Flo-Rad groove, and importantly, they are +.150 inch over standard size, which is crucial for certain engine builds where increased valve lift or clearance is needed.

Ferrea is known for well-built engine components, and these valves are no exception. The hollow stem design helps reduce overall weight, which can lead to improved valve train stability at higher RPMs. The material and construction are intended to handle the demands of performance engine applications. The +.150 inch over size means these are specifically chosen for engines that have been machined to accept larger valves, often part of a performance rebuild or upgrade.
