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.
