Ferrea Ford 351 W 1.48in 11/32in 5.075in 14 Deg S-Flo 6000 Series Exhaust Valve - Set of 8

If you're rebuilding the top end of your Ford 351 Windsor engine, especially for performance applications, you'll want to make sure your exhaust valves can handle the heat and pressure. These Ferrea S-Flo 6000 Series exhaust valves are built for that kind of work. They're designed to improve airflow into the cylinder, which is key for getting more power out of your engine.

Ferrea uses a special heat treatment process on these valves, making them well-built and able to withstand higher temperatures and stresses than stock valves. The S-Flo design means the valve face is shaped to help gases flow more smoothly around it, reducing turbulence and increasing efficiency. Each valve measures 1.48 inches across the face, has a 11/32-inch stem diameter, and is 5.075 inches long, making them a solid option for many 351 Windsor builds. This set includes eight valves, enough for a complete V8 engine.
