Ferrea Chevy/Chry/Ford SB 1.6in 5/16in 5.01in 14 Deg Flo Rad Grv +.100 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 1.6 inches across the head and has a 5/16 inch stem. They are 5.01 inches long and feature a 14-degree valve seat angle with a relieved groove for better airflow.

These valves are built with a hollow stem design, which helps reduce weight and allows for improved valve train stability at higher RPMs. The head diameter of 1.6 inches is a common size for many performance small-block applications, and the +.100 inch length over standard can be useful for certain cylinder head porting or piston-to-valve clearance setups. Ferrea is known for well-built engine components, and these valves are a solid option for rebuilding or upgrading your SB engine's top end.

When rebuilding your engine, ensure you have the correct valve springs and retainers to match these valves' characteristics. Proper installation is key to performance and longevity.
