Ferrea Chevrolet BB 2.19in 3/8in 5.35in 12 Deg S-Flo +.130 Competition Plus Intake Valve - Set of 8

If you're rebuilding the top end of your Chevrolet Big Block engine, especially for performance applications, you need intake valves that can handle the demands. These Ferrea Competition Plus intake valves are built for that purpose. They're designed to work with your existing valve guides and seats, making them a solid choice for an engine overhaul.

Ferrea uses high-quality steel for these valves, which is then heat-treated for improved durability. The valve face measures 2.19 inches, and the stem is 3/8 inch with a length of 5.35 inches. This specific set is +.130 inches larger than stock, which can help improve airflow into the combustion chamber. The S-Flo design also helps with gas flow, and the 12-degree tulip shape is a common feature for performance applications.

This set includes eight intake valves, enough for a standard V8 engine. When installing, make sure to check your valve spring pressures to ensure they are compatible with the valve weight and intended RPM range.
