Ferrea Chevy SB 1.625in 11/32in 5.16in 0.25in 15 Deg S-Flo +.200 6000 Series Exhaust Valve- Set of 8

These Ferrea 6000 Series exhaust valves are made from a high-strength stainless steel alloy, specifically chosen for its ability to withstand the high temperatures and stresses found in performance Chevy SB engines. Each valve measures 1.625 inches in diameter with a 11/32 inch stem, and this particular set is +.200 inches longer than stock, which can be useful for certain cylinder head modifications or valvetrain setups.

The S-Flo design features a specialized undercut stem and a radiused face, which helps improve airflow into the cylinder by reducing turbulence. This updated design can lead to a more efficient burn and potentially improved engine performance. The 15-degree seat angle is also a common performance feature that can aid in sealing and airflow. This set includes eight valves, enough for a complete V8 engine.
