Ferrea Chevy/Chry/Ford SB 1.625in 11/32in 4.96in 0.29in 15 Deg Titanium Comp Exhaust Valve- Set of 8

This set includes eight Ferrea Comp Exhaust Valves, specifically designed for Chevy, Chrysler, and Ford Small Block (SB) engines. These valves feature a 1.625-inch head diameter, a 11/32-inch stem diameter, and a length of 4.96 inches, with a 0.29-inch margin and a 15-degree seat angle. The use of titanium in their construction is a key factor in their performance and durability.

Titanium is significantly lighter than traditional steel used in valves. This reduced mass means the valve can open and close faster, allowing your engine to achieve higher RPMs without valve float. It also puts less stress on the valve springs and the rest of the valvetrain. Ferrea is known for its well-built engine components, and these valves are no exception, offering a solid option for builders looking to maximize their engine's potential. The precise dimensions ensure they fit correctly within the valve guides and seat properly in the cylinder head.

When rebuilding or upgrading a performance engine, especially one that will see high RPMs, using lightweight, strong valves like these can make a notable difference. Ensure you have the correct valve springs and retainers that are compatible with the valve's weight and operating characteristics for optimal performance and longevity. Refer to the manufacturer's installation instructions for specific details regarding installation and compatibility with other valvetrain components.
