Ferrea Chevrolet BB 1.88in 11/32in 5.45in 0.25in 22 Deg S-Flo Super Alloy Exhaust Valve - Set of 8

If you're rebuilding the top end of a Chevrolet Big Block engine, especially one built for serious performance, you'll want to pay close attention to the valves. These Ferrea S-Flo exhaust valves are designed to handle the demands of high-RPM operation and improved airflow. The S-Flo design is a unique feature that helps improve airflow characteristics into the combustion chamber.

Each valve in this set of eight is made from a super alloy material, chosen for its strength and resistance to high temperatures found in performance engines. They feature a 1.88-inch face diameter and a 5.45-inch overall length, with a 0.25-inch margin and a 22-degree seat angle, all built around an 11/32-inch stem diameter. This combination is intended to work well with many performance cylinder head port designs for Big Block Chevy applications.

When you're putting together a high-performance engine, using well-built components like these valves is crucial for reliability and performance. Make sure to check your cylinder head specifications to ensure these valves are the right fit for your specific build.
