Ferrea Chevrolet SB 2.1in 5/16in 5.160in 12 Deg S-Flo +.200 Competition Plus Intake Valve - Set of 8

If you're rebuilding the top end of your Chevrolet Small Block engine and looking for improved airflow, these Ferrea Competition Plus intake valves are a solid choice. Designed for performance applications, these valves feature a 2.1-inch head diameter and a 5/16-inch stem, with a length of 5.160 inches. They are +.200 inches oversize, which can help increase the intake port volume and allow for better air and fuel mixture into the combustion chamber.

Ferrea is known for making well-built valvetrain components, and the Competition Plus line is designed for durability and performance. The valves are made from high-strength steel and feature a swirl-polished stem for reduced friction and improved airflow. The 12-degree seat angle is a common specification that works well with many cylinder head designs. This set includes eight valves, enough for a complete V8 engine.
