Ferrea Chevy/Chry/Ford SB 1.65in 11/32in 5.45in 25 Deg Tulip +.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 Exhaust Valves are a solid choice. This set includes eight valves, each measuring 1.65 inches in diameter with an 11/32-inch stem and a total length of 5.45 inches. They are designed with a 25-degree tulip face and are +.500 inches longer than stock, which is important to consider when planning your valvetrain setup.

Ferrea uses titanium for these valves, which is notable for its strength and light weight. This combination helps reduce the stress on your valvetrain components, especially at higher RPMs. The titanium construction also offers good resistance to heat and wear, which is crucial for exhaust valves that operate under demanding conditions. The 25-degree tulip face is a common design that helps with sealing and airflow into the combustion chamber.

When installing these valves, remember they are +.500 inches longer than stock. This means you'll need to ensure your rocker arms and pushrods are correctly adjusted to achieve proper geometry and valve lift. It's always a good idea to consult your engine's specific service manual or a trusted builder for guidance on setting up your valvetrain with these longer valves to get the most out of your engine build.
