SBM C/6 2.020 Intake Valves 3/8 x 4.980

The Ferrea 6000 Series Competition Intake Valves are designed for high-performance applications, including Drag and Oval Track racing. These valves offer increased fatigue resistance and tensile strength over competitors. They are manufactured using an exclusive two-step slow forging process with EV8 stainless steel.

Each valve features a swirl-polished head, hard chrome stems, and friction-welded hard tips, along with a special heat-treatment and stress-relieving process. The 12-degree Super Flo design improves flow without compromising reliability, making them suitable for engines with high spring pressures and roller cams.
