BC valves feature a one-piece design with friction-welded stellite tips for optimum performance. Each valve is manufactured from high-grade, heat-resistant stainless steel to ensure reliability in high boost and/or high RPM applications. The back-cut stem over the head not only reduces overall weight for increased RPM potential but also significantly improves air/fuel flow in and out of the combustion chamber. Each valve is fully machined and features a spiral-polished finish on the underside of the head.
