Ferrea Chevrolet BB 2.19in 11/32in 5.3in 12 Deg S-Flo +.050 Competition Plus Intake Valve - Set of 8

If you're rebuilding the top end of a Chevrolet Big Block engine and looking for improved airflow, these Ferrea Competition Plus intake valves are a solid option. They're designed to handle the demands of performance builds, helping your engine breathe easier and make more power.

These valves feature a 2.19-inch diameter head, which is larger than stock, allowing more air into the combustion chamber. The 11/32-inch stem diameter and 5.3-inch overall length are common dimensions for many Chevrolet Big Block applications. Ferrea uses high-quality steel for these valves, heat-treating them for durability and resistance to wear. The S-Flo design with a 12-degree seat angle helps improve flow characteristics, especially in performance cylinder heads. This set includes eight valves, enough for a typical V8 engine.

When installing these valves, ensure your valve guides and seals are in good condition. The +.050 designation indicates these valves are 0.050 inches longer than standard, which can be important for valve train geometry in certain builds. Always refer to your engine's specific service manual for correct installation procedures and clearances.
