Ferrea Chevy/Chry/Ford SB 1.625in 11/32 5.01in 14 Deg S-Flo Rad Grv +.100 Hollow Exh Valve- Set of 8

If you're rebuilding the top end of your Chevy, Chrysler, or Ford small block engine, you'll want to make sure your exhaust valves can handle the heat and pressure. These Ferrea F1025P exhaust valves are built for that job, featuring a hollow stem design to reduce weight and improve valvetrain stability at higher RPMs. The 1.625-inch head diameter and 5.01-inch overall length are common dimensions for many SB applications, and the 14-degree swirl-flow radius groove helps promote better air-fuel mixture movement in the combustion chamber.

Ferrea uses strong, well-built materials for their valves, and these are no exception. The +.100 inch oversize on the stem diameter means they're designed to be machined into a block that's been bored out or has had its guides reamed to accommodate the larger size, ensuring a snug fit and proper sealing. This set includes eight valves, enough for a typical V8 engine, and they're a solid option for performance builds where reliability and improved airflow are key.
