K-Series Ferrea 6000 Valves STD Size Intake & Exhaust Set

Ferrea 6000 Series Valves are one of the most cost effective valve applications on the market today. They are designed to withstand high rpm and high spring pressure at a budget price. Ferrea uses a 2 step slow forging technique applied to special alloys to create these valves. They are heat treated and stress relieved with a swirl polished head.

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 our competitor's best offerings.

To manufacture the valves we use our 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. We finish with a swirl polished head. The valves feature flow improvements to deliver the power needed for today's sophisticated racing engines.
