Ferrea Chevrolet LSX DR Head 1.625in 0.31in 6.4in 24 Deg Taper Flo Rad Grv Hollow Exh Valve-Set of 8

If you're rebuilding the top end of your Chevrolet LSX engine and looking for improved airflow through the exhaust ports, these Ferrea DR series hollow exhaust valves are a solid option. Designed specifically for high-performance LSX applications, these valves are built to handle the demands of aggressive engine builds. The 1.625-inch diameter and 6.4-inch length are optimized for many popular LSX cylinder heads, and the 24-degree taper flow radius groove helps improve gas flow efficiency as the valve opens and closes.

What sets these valves apart is their hollow stem construction. This design significantly reduces weight compared to solid valves, which helps the valvetrain operate more reliably at higher RPMs by reducing inertial forces. Ferrea is known for making well-built valvetrain components, and these exhaust valves are no exception. They are constructed from high-grade materials to ensure durability and consistent performance under demanding conditions. This set includes eight valves, enough for a complete V8 engine.
