Ferrea Chevy/Ford BB 2.25in 11/32in 5.271in 12 Deg S-Flo +.050 Hollow Int Valve- Single (D/S Only)

This is a Ferrea F1048P-1 hollow intake valve, designed for Chevy and Ford big block engines. It features a 2.25-inch head diameter and a 5.271-inch overall length, with a 11/32-inch stem. The valve is built with a hollow stem to reduce weight, which can help the valvetrain operate more efficiently at higher RPMs. This particular valve is intended for single, driver's side (D/S) applications and is +.050 inches in size, meaning it's slightly larger than a standard valve to accommodate engine rebuilds or modifications.

Ferrea uses strong materials to build their valves, aiming for durability and reliable performance. The S-Flo design is a specific profile that helps improve airflow into the cylinder, contributing to better combustion. The 12-degree seat angle is also a common specification that works well with many cylinder head designs. This valve is a solid option if you're working on a performance-oriented big block build where valvetrain stability and airflow are important considerations.
