Ferrea Chevrolet SB 2.125in 5/16in 5.010in 12 Deg Flo +.100 Competition Plus Intake Valve - Set of 8

These are Ferrea Competition Plus intake valves, designed for Chevrolet Small Block engines. This set includes eight valves, each measuring 5.010 inches in length with a 2.125-inch diameter face and a 5/16-inch stem. They are built with a 12-degree swirl polished face and are +.100 inches longer than stock to accommodate specific engine builds.

Ferrea uses high-quality steel for these valves, heat-treated and polished to help with airflow and durability. The swirl-polished face is a notable detail that helps reduce carbon buildup and improve gas flow characteristics. These valves are a solid option if you're rebuilding the top end of your Chevrolet SB and need reliable components that can handle increased performance demands.

When installing these valves, remember they are designed for specific engine configurations, so ensure your camshaft and valve springs are compatible with the +.100 inch length and the 12-degree seat angle.
