Ferrea Chevy SB 2.125in 11/32in 5.45in 12 Deg S-Flo +.500 Competition Plus Intake Valve - Set of 8

These Ferrea Competition Plus intake valves are built for Chevy small block engines, measuring 2.125 inches in diameter with a 11/32 inch stem and a 5.45 inch overall length. The S-Flo design features a 12-degree seat angle, which helps improve airflow into the cylinder. This set includes eight valves, designed to be a direct replacement for your engine's intake valves.

Ferrea uses a high-quality steel alloy for these valves, chosen for its strength and ability to withstand the heat and stress inside the combustion chamber. The Competition Plus series is a well-known option for builders looking for improved performance over stock components. The +.500 sizing indicates these valves are slightly longer than standard, which can be beneficial for certain camshaft profiles or cylinder head modifications where valve lift needs to be accommodated. Proper installation is key to ensuring these valves perform as intended.
