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