Ferrea Chevrolet BB 1.88in 11/32in 5.35in 0.25in 15 Deg S-Flo 5000 Series Exhaust Valve - Set of 8

If you're rebuilding the top end of your Chevrolet big block engine, you'll want to make sure your exhaust valves can handle the heat and pressure. These Ferrea 5000 Series S-Flo exhaust valves are built for that kind of work. They are designed to help exhaust gases flow out of the cylinder more efficiently, which can make a difference in how your engine performs.

Each valve in this set of eight features a 1.88-inch head diameter and a 5.35-inch overall length, with a 0.25-inch stem diameter. The S-Flo design and 15-degree seat angle are part of what helps improve gas flow. Ferrea uses strong materials to make these valves, aiming for durability under demanding conditions inside your engine.
