Ferrea Chevy/Chry/Ford SB 1.625in 5/16in 5.01in 14 Deg Flo Rad Grv +.100 Hollow Exh Valve - Set of 8

These Ferrea exhaust valves are made from a high-strength alloy, specifically chosen for their ability to withstand the high temperatures and pressures found in performance engine builds. The hollow stem design helps reduce overall valve weight, which can lead to improved valve train stability at higher RPMs. This set includes eight valves, each measuring 1.625 inches in diameter with a 5/16 inch stem and a total length of 5.01 inches.

The valves feature a 14-degree face angle and a relieved groove, designed to help improve airflow and reduce valve float. They are also +.100 inch oversize, meaning they are larger than standard valves and are intended for applications where the valve seats have been machined to accept them, often during an engine rebuild or performance upgrade. This oversize dimension can help improve sealing and potentially increase compression in certain setups.

When rebuilding a small block Chevy, Chrysler, or Ford engine, especially one intended for performance use, these valves are a solid option. Their construction and design are geared towards handling the demands of a performance engine, offering a good balance of durability and weight savings for the valve train.
