Ferrea Chevrolet BB 2.19in 3/8in 5.271in 12 Deg S-Flo +.050 Competition Plus Intake Valve - Set of 8

Ferrea Competition Plus intake valves are a solid option for your Chevrolet Big Block engine build. This set includes eight valves, each measuring 5.271 inches in length with a 2.19-inch head diameter and a 3/8-inch stem. They are designed with a 12-degree S-Flo face, which helps improve airflow into the cylinder.

These valves are made from high-strength stainless steel, chosen for its durability under high temperatures and pressures common in performance engines. The Competition Plus line is built for demanding applications where reliability and consistent performance are key. Each valve is also +.050 inches oversized on the head diameter, which can be beneficial for maximizing airflow in modified cylinder heads. This specific sizing requires careful attention during cylinder head porting and valve seat installation to ensure proper fitment and sealing.

When rebuilding or upgrading your Chevrolet Big Block's top end, using well-made valves like these can make a notable difference in performance and longevity. Ensure your valve guides and seats are properly prepared to match these valves for optimal results.
