Ferrea Chevrolet SB 1.6in 11/32in 5.3in 0.25in 12 Deg S-Flo Comp Plus Exhaust Valve - Set of 8

If you're rebuilding the top end of your Chevrolet Small Block engine and need exhaust valves that can handle the demands of performance, these Ferrea Comp Plus valves are a solid option. They're built to work with S-Flo cylinder heads, which feature a unique port shape designed for improved airflow. These valves are specifically sized for common SB applications, measuring 1.6 inches across the head and having a 0.25-inch undercut under the head to help reduce weight and improve flow dynamics.

Ferrea is known for making well-built valvetrain components, and these Comp Plus exhaust valves are no exception. They feature a 5.3-inch overall length and a 11/32-inch stem diameter, common dimensions for many Chevrolet SB builds. The 12-degree back angle on the valve face is designed to help create a good seal in the combustion chamber, which is crucial for consistent performance. This set includes eight valves, enough for a complete V8 engine.
