Ferrea Chevrolet BB 1.94in 3/8in 5.4in 15 Deg S-Flo +.050 Competition Plus Exhaust Valve - Set of 8

These Ferrea Competition Plus exhaust valves are built for Chevrolet big-block engines, measuring 1.94 inches in diameter and 5.4 inches in length. They feature a 3/8 inch stem and are designed with a 15-degree S-Flo angle, which helps improve airflow by reducing turbulence as the valve opens. This specific set is +.050 inches oversized, meaning they are intended for engines that have been bored out to accommodate larger valves, often during a performance rebuild.

Constructed from high-grade steel, these valves are well-built to withstand the high temperatures and pressures found in performance big-block applications. The S-Flo design is a notable feature that contributes to improved cylinder filling and exhaust scavenging, making them a solid choice for builders looking to extract more power from their Chevrolet V8. The +.050 sizing indicates they are part of a more involved engine build where cylinder walls have been machined to accept them.

When rebuilding or modifying your Chevrolet big-block, choosing the right valvetrain components is crucial for reliability and performance. This set of eight exhaust valves from Ferrea offers a combination of robust construction and an advanced airflow design to help your engine breathe better.
