Ferrea Chevy SB 1.6in 11/32in 5.01in 0.25in 12 Deg S-Flo +.100 6000 Series Exhaust Valve - Set of 8

These Ferrea 6000 Series exhaust valves are built with a specific +.100 inch oversize on the stem diameter, measuring 11/32 inches, which is a common size for many Chevy small block applications. The 1.6-inch head diameter and 5.01-inch overall length are designed to work within specific cylinder head port volumes and piston valve reliefs, especially when you're rebuilding the top end of your engine. The 12-degree seat angle is also a key detail for proper sealing against the valve seat.

Ferrea uses high-quality steel alloys for their valves, and these 6000 Series units are no exception. They are constructed to handle the heat and stress of exhaust gases in performance-oriented small block Chevy engines. The S-Flo design is intended to improve airflow compared to standard valves, which can contribute to better engine breathing and performance. This set includes eight valves, enough for a complete V8 engine.

When you're putting together a performance small block Chevy, choosing the right valvetrain components is crucial. These Ferrea valves are a solid option for builders looking for reliable performance and durability. Make sure to check your cylinder head's valve guide dimensions to confirm compatibility with the 11/32 inch stem size.
