Billet Ford Heads
The demand for more power in a racing engine is never ending. The best area to search for power in the past has traditionally been the cylinder head. The problem is many castings have reached their developmental limit. Power levels have also grown so high that castings no longer can stand the temperatures and pressures involved for very long, having to be replaced every few races. In some applications castings are not stiff enough to resist flexing and lifting!! So Don Losito thought it was necessary to start from a clean slate, from a stronger material with unlimited options. With the capabilities of Ultra Pro Machining's 5-Axis CNC machines a cylinder head made from one solid aluminum billet with a complete water jacket was possible. What this means is a cylinder head that is incredibly stiff to resist lifting and flexing. Tougher material that resists softening much better than castings. Most importantly, complete freedom in port design, chamber design, valve positioning, spark plug positioning, and water jacket placement. If a new port design interferes with the water jacket on one of our billet heads we simply reposition the water jacket. This line of cylinder heads has been a powerful tool for engine builders. Our 9 degree Ford made possible by the billet process has consistently netted engine builders many advantages over the Ford cast heads. They have been in production for over 12 years now with hundreds of heads currently racing with no problems. Customers running our turbo/supercharged head have yet to break one while producing 2500+ horsepower. These heads have been racing and winning in nearly every application including, Dirt Late Models, Offroad Trucks, ARCA, and many Drag Racing series. Also available is a port for high performance street engines, which responds well over a broader range than the race heads. For extreme Drag Racing applications we have a non-water jacketed 18-bolt option. To make sure your heads are perfect for you several valve sizes and seat angles are available. All heads feature oversized valve seats made from either beryllium copper or ductile iron. The valve job is cut by a Serdi valve seat-cutting machine to insure perfect concentricity.
