Ferrea Chevrolet BB 1.94in 11/32in 5.425in 15 Deg S-Flo +.100 6000 Series Exhaust Valve - Set of 8

Ferrea has a solid reputation for making high-performance engine components, and these 6000 Series exhaust valves are a great example of that. They're built specifically for Chevrolet Big Block engines, designed to handle the demands of performance builds. You get a set of eight valves, each featuring a 1.94-inch head diameter and a 5.425-inch overall length. This particular set is +.100 inches oversize, which is important to note if you're rebuilding or modifying your engine's cylinder heads.

The S-Flo design is a notable feature, meaning the valves have a special undercut stem that helps improve airflow into the cylinder. This can lead to better combustion efficiency and a bit more power. The 15-degree seat angle is also a common performance specification that works well with many aftermarket cylinder heads. These valves are well-built and intended for engines where reliability and improved airflow are key goals.
