The 6000 Series Competition Valves are designed to provide excellent reliability in an environment of high spring pressures, at a budget price. They have higher fatigue resistance and tensile strengths than their competitor’s best offerings. To manufacture the valves Ferrea uses their exclusive two-step slow forging process using EV8 stainless steel on both intake and exhaust valves. They provide a special heat-treatment and stress relieving process, along with hard chrome stems and friction-welded hard tips, and finish with a swirl polished head. The valves feature flow improvements to deliver the power needed for today’s sophisticated racing engines.
