Ferrea Chevy SB 2.125in 11/32in 5.06in 12 Deg S-Flo +.150 Competition Plus Intake Valve - Set of 8

If you're working on a Chevy small block engine and looking to improve its breathing, these Ferrea Competition Plus intake valves are a solid choice. This set includes eight valves, each measuring 2.125 inches across the head and 5.06 inches in overall length, with a 12-degree seat angle. They are designed for a 11/32-inch stem diameter, which is common for many performance Chevy SB applications.

Ferrea is known for making well-built valvetrain components, and the Competition Plus line is designed for engines that see a lot of use and demand better airflow. The valves are made from strong materials to handle the heat and stress inside the combustion chamber. The +.150 designation indicates these valves are 0.150 inches longer than stock, which can be useful when using certain cylinder heads or camshaft combinations to achieve proper valve-to-piston clearance and valve train geometry. Always double-check your specific cylinder head and camshaft setup to ensure these longer valves will work correctly.
