Ferrea 6000 Series Competition 1.940" Intake Valves (Set of 8) - SB Chevy - 11/32" Stem Diameter - 5.010" Length - 11/32" Stem Diameter - 5.010" Length

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 our competitor's best offerings. These valves can be used in Drag and Oval Track racing applications. To manufacture the valves, we use our exclusive two-step slow forging process using EV8 stainelss 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. We finish with a swirl polished head. The valves feature flow improvements to deliver the power needed for today's sophisticated racing engines.
