BBC S/F 2.190in Intake Valves

The BBC S/F 2.190in Intake Valves by MANLEY are precision-engineered components designed for big-block Chevrolet engine builders and performance enthusiasts who prioritize reliability in high-performance applications. These valves are essential for managing the fuel-air mixture during the intake stroke, making them crucial for both rebuilding classic engines and enhancing performance in modern builds.

Featuring a head diameter of 2.190 inches, these intake valves are optimized for flow efficiency and structural integrity, allowing for maximum charge density while ensuring effective seat sealing. The S/F designation indicates a robust steel construction that can endure high thermal cycling and aggressive cam profiles, providing durability against warping and pitting.

Ideal for a variety of applications, including street, strip, marine, and industrial powertrains, these valves are suitable for both carbureted and fuel-injected big-block Chevrolet setups. Engine builders will appreciate the superior flow characteristics compared to factory valves, making them a reliable choice for performance upgrades.
