Ferrea Chevy/Chry/Ford SB 1.625in 11/32in 5.45in 0.29in 15 Deg +.500 Ti Comp Exhaust Valve- Set of 8

If you're rebuilding the top end of your Chevy, Chrysler, or Ford small block engine, these Ferrea Competition Plus exhaust valves are a solid choice. This set includes eight valves, each measuring 1.625 inches in diameter with a 0.29-inch undercut and a 5.45-inch overall length. The 11/32-inch stem diameter is a common size for many performance applications, and these valves are designed to handle the demands of high-performance engines.

Ferrea uses high-quality titanium for these valves, which offers a good strength-to-weight ratio. This helps reduce valve float at higher RPMs and can contribute to improved engine response. The valves are also +.500 inches longer than stock, which is important to consider when setting up your valvetrain geometry, especially with aftermarket camshafts and cylinder heads. The 15-degree swirl-polished face is designed to help improve airflow into the combustion chamber and aid in keeping the valve clean.

When installing these valves, pay close attention to the valvetrain geometry to ensure proper lift and clearance. Because these are longer than stock, you may need to adjust rocker arm geometry or consider different pushrods to achieve the correct setup. It's always a good idea to consult your cylinder head manufacturer's specifications or a trusted performance engine builder to confirm the ideal valvetrain setup for your specific application.
