Ferrea Chevrolet BB 2.25in 3/8in 5.271in 12 Deg S-Flo +.050 Competition Plus Intake Valve - Set of 8

Ferrea is known for making high-performance engine components, and their Competition Plus valves are a popular choice for builders looking to get the most out of their Chevrolet Big Block engines. This set of eight intake valves is designed to handle the demands of performance builds, whether you're working on a street-strip machine or a dedicated race engine.

Each valve in this set measures 2.25 inches across the head and has a 5.271-inch overall length with a 3/8-inch stem diameter. They are manufactured to a 12-degree angle and are +.050 inches larger than stock, which can help improve airflow into the combustion chamber. The Competition Plus line uses a specific alloy and heat treatment process to ensure durability under high stress and temperature conditions.

When rebuilding the top end of your Chevrolet Big Block, using well-built valves like these from Ferrea is crucial for reliable performance. Make sure to check your valve guide dimensions and piston-to-valve clearance after installation, especially when using larger valves.
