Ferrea Competition Plus Super Alloy Valves are Ferrea's Top of the Line Valve with all of the features, and is made from best quality material available. They are designed to withstand high rpm and high spring pressure at a fair price for a top of the line valve. 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. Ferrea makes several B-Series Valve part numbers and we try to keep many of the popular part numbers in stock. Just select which part number best fits your application from the list below, and include that part number in the paypal notes section of your payment.  

The Special Alloy that these valves are made from is designed to handle the high heat of turbo, nitrous, or supercharged applications. It is strong enough to handle high horsepower at high rpm and light enough for use in all motor applications.
