Ferrea Chevrolet BB 2.25in 11/32in 5.271in 12 Deg S-Flo +.050 6000 Series Intake Valve - Set of 8

Ferrea is well-known for making high-performance valvetrain components, and this set of 6000 Series intake valves is a prime example of their work for Chevrolet Big Block engines. These valves are built to handle the demands of performance builds, ensuring your engine breathes efficiently under stress.

Each valve features a 2.25-inch head diameter and a 5.271-inch overall length, with a 11/32-inch stem. The S-Flo design is intended to improve airflow into the combustion chamber, which can lead to better performance. This particular set is +.050 inch oversized, meaning they are designed to fit into a block that has been machined to accept larger valves, often part of a performance rebuild. The 12-degree seat angle is also a common performance feature that can help with sealing and airflow.

This set includes eight intake valves, enough for a complete V8 engine. If you're rebuilding the top end of your Chevrolet Big Block and looking for valvetrain components that offer improved airflow and are built for performance, this Ferrea set is a solid option.
