Ferrea Ford 351 W 1.78in 11/32 5.075in 12 Deg S-Flo 6000 Series Intake Valve - Set of 8

If you're rebuilding the top end of your Ford 351 Windsor engine, getting the right valves is key to making sure everything seals up tight and breathes well. These Ferrea 6000 Series intake valves are built for performance builds where airflow is critical. They feature a 1.78-inch diameter face, which is larger than stock, to help pull more air into the cylinder.

Ferrea makes these valves from a strong, high-quality steel alloy that's designed to handle the heat and stress of performance engines. The S-Flo design means they have a specialized shape that helps improve airflow right where it matters, and the 12-degree seat angle is a common choice for many performance heads. Each valve measures 5.075 inches long and has an 11/32-inch stem diameter, fitting many popular aftermarket cylinder heads for the 351 Windsor. This set includes eight valves, enough for a full V8 engine.
