Ferrea Chevrolet BB 2.35in 11/32in 5.625in 12 Deg +.400 Competition Plus Intake Valve - Set of 8

If you're rebuilding the top end of a Chevrolet Big Block engine, especially for performance applications, new intake valves are a critical component. These Ferrea Competition Plus intake valves are built to handle the demands of a performance engine, ensuring proper airflow into your cylinders. They are designed with a 2.35-inch head diameter and a 5.625-inch overall length, with a 12-degree valve seat angle.

Ferrea is known for making well-built valvetrain components, and this set of eight intake valves is no exception. They feature a +.400-inch stem height, which is useful when you're matching them with specific camshafts or cylinder heads to achieve optimal valve lift and piston-to-valve clearance. The Competition Plus line is a popular choice for builders looking for reliable performance without going to the extreme expense of their highest-end racing valves.

When installing these valves, make sure your valve guides are in good condition and properly sized for the 11/32-inch stem diameter. It's also important to check your piston-to-valve clearance carefully, especially if you've modified your cylinder heads or are using a high-lift camshaft, to ensure the +.400-inch stem height works correctly with your build.
