Ferrea Chevrolet LS1 2.08in 0.3135in 5in 12 Deg S-Flo +.100 Rad Grv 6000 Series Int Valve - Set of 8

These Ferrea 6000 Series intake valves feature a 2.08-inch head diameter and are designed for Chevrolet LS1 engines. The valves are made from a high-strength material, specifically a high-grade stainless steel alloy, chosen for its ability to withstand the high temperatures and stresses found in performance engine builds. The +.100" oversized head diameter can help improve airflow into the combustion chamber, especially when paired with porting work on the cylinder heads.

The S-Flo design incorporates a special undercut on the valve stem, which helps reduce valve shrouding and further promotes better airflow. This design, combined with the 12-degree seat angle and the radial groove, contributes to improved performance and efficiency. Each valve measures 5 inches in length and has a 0.3135-inch stem diameter, ensuring compatibility with many popular LS1 valvetrain components. This set includes eight intake valves, enough for a complete V8 engine.
