Ferrea Chevy SB 2.125in 11/32in 4.96in 12 Deg S-Flo +.050 Competition Plus Intake Valve - Set of 8

This set includes eight Ferrea Competition Plus intake valves, specifically sized for Chevy Small Block engines. Each valve measures 2.125 inches across the head and has a 4.96-inch overall length with a 11/32-inch stem diameter. These valves are +.050 inch oversize, meaning they are designed to fit into a block that has been machined to accommodate this larger size, often during an engine rebuild or performance upgrade.

Ferrea's Competition Plus line is known for its well-built construction, using high-quality materials to handle the demands of performance engines. The S-Flo design is intended to improve airflow into the combustion chamber, which can contribute to better engine performance. The 12-degree swirl-polished face is a detail that helps reduce carbon buildup and further aids in smooth airflow. These valves are a solid option when you're rebuilding a Chevy SB engine and looking for components that offer improved flow characteristics and durability.

When installing these valves, ensure your valve guides and seats are properly prepared for the +.050 oversize dimension. It's always a good idea to consult your engine builder or a trusted mechanic to confirm all specifications before installation.
