Ferrea Chevy/Chry/Ford SB 1.625in 11/32in 5.14in 0.29in 25 Deg +.200 Ti Comp Exhaust Valve- Set of 8

This set includes eight Ferrea Competition Plus exhaust valves, specifically designed for Chevy, Chrysler, and Ford small block engines. These valves feature a titanium-nitride coated stem for improved durability and reduced friction, a common upgrade for high-performance builds where reliability under stress is key. The valves measure 1.625 inches in diameter with a 0.29-inch margin and a 5.14-inch overall length, featuring a 25-degree seat angle and a +.200-inch oversized stem diameter for enhanced flow and compatibility with modified cylinder heads.

Crafted from high-strength steel with a specialized coating, these valves are built to withstand the demanding conditions of performance engines. The titanium-nitride coating on the stem helps to reduce wear and improve the valve's ability to slide smoothly within the valve guide, which is crucial for maintaining consistent engine performance at higher RPMs. The oversized stem also allows for more material in the valve head, contributing to better sealing and heat dissipation. This set is a solid choice for engine builders looking to optimize their small block's breathing capabilities.

When installing these valves, ensure your cylinder heads are prepared to accept the +.200-inch oversized stems, which may require reaming the valve guides. It's also recommended to use high-quality valve springs and retainers that are matched to the valve's weight and the engine's intended operating range to ensure proper valve control and prevent valve float. This set is designed for performance applications where maximizing exhaust flow and durability is a priority.
