Ferrea Chevy SB 2.1in 11/32in 4.96in 12 Deg S-Flo +.050 Competition Plus Intake Valve - Set of 8

These Ferrea Competition Plus intake valves measure 2.1 inches across the face and have a 11/32-inch stem diameter, with an overall length of 4.96 inches. They are designed for Chevy Small Block engines and feature a 12-degree seat angle, a common specification for many performance applications. The S-Flo design is intended to improve airflow into the cylinder.

Built with high-quality steel, these valves are made to handle the demands of performance engines. The +.050 specification indicates they are 0.050 inches larger in diameter than a standard valve, which can help increase airflow. Ferrea is known for making well-built valvetrain components, and this set of eight valves is a solid option for anyone rebuilding or upgrading their Chevy SB cylinder heads.

When installing these valves, ensure your valve guides and seats are properly prepared to match the valve dimensions for optimal sealing and performance. This set is designed to be a direct replacement for specific Chevy SB applications, so double-check your engine's requirements.
