Ferrea Chevrolet SB exhaust valves are a solid option for rebuilding or upgrading your small-block Chevy engine. This set includes eight valves, each featuring a 1.625-inch head diameter and a 5/16-inch stem for a 5.350-inch overall length. The 14-degree S-Flo design helps improve airflow into the cylinder.

These valves are part of Ferrea's Comp Plus line, indicating they are built for enhanced durability and performance. The +.400 Comp Plus designation means they are designed to work with specific camshaft profiles and valve spring pressures, offering improved valve lift capability over standard valves. The material and construction are chosen to withstand the heat and stress of combustion, making them a reliable choice for performance builds.

When installing these valves, ensure you have the correct valve spring and retainer combination to match the Comp Plus specifications for optimal performance and longevity. Proper setup is key to getting the most out of these well-built components.
