Cylinder Heads
Cylinder Heads For Twin Cam Harley-Davidson®
We CNC machine the combustion chamber to put it back in the center of the cylinder where it belongs, casting core shift and the power robbing problems of non balanced combustion associated with it are eliminated.We full port the intake and exhaust runners for maximum velocity and CFM for cam lifts from stock up to .600" lift.We replace the stock guides, valves, seals and springs with the highest performance components on the market.We start with Black Tulip intake and exhaust valves. These superb valves feature the highest flow level on the market. They are one piece forged from a racing grade stainless steel alloy in a hard black oxide finish. Each valve has a bearing quality hardened tip at the end of the stem to prevent premature wear with high-lift applications. The Tulip Valve design also features a 45o angle below the lock groove to reduce the stress in this area and to facilitate the valve seal installation. Each valve is heat treated with a special process and the stem is center less ground to a micro finish for a longer life. The smooth dish face of the intake valves promotes a better combustion in the chamber while the exhaust valves features a thick margin for better flow. All Chambers and radiuses on both intake and exhaust have been optimized for better airflow.They are fitted into manganese bronze alloy guides. The two principal advantages of this alloy are superior heat transfer and the ability to fit the guides at a tighter clearance for a better oil film control and longer life.And topped with Viton valve seals that resist higher temperatures and provide superior sealing then the OEM type of seal found in lesser quality cylinder heads.All these components are controlled with valve springs manufactured from the finest quality spring wire, made from an ultra clean high silicon and vanadium alloy wire, the best alloy available on the market for high lift and endurance applications. They are held with the strongest and the most durable chromoly 4140 steel retainers and anchored by jumbo 10 deg locks for superior valve control.Combustion chamber volume is set to accommodate the cam of your choice at no charge.Compare Syke Performance cylinder heads to the competition and you will see the difference, bolt on a set of Syke Performance cylinder heads and you will feel the difference.We CNC machine the combustion chamber to put it back in the center of the cylinder where it belongs, casting core shift and the power robbing problems of non balanced combustion associated with it are eliminated.We full port the intake and exhaust runners for maximum velocity and CFM for cam lifts from stock up to .600" lift.We replace the stock guides, valves, seals and springs with the highest performance components on the market.We start with Black Tulip intake and exhaust valves.
