Super Stock Head Kit

Assembled Super Stock head kit for 1991 – ’03 Sportster® models feature specially shaped combustion chamber and contoured piston dome are what make makes these heads produce power. The increased “squish” area of this design sets up a controlled turbulence in the combustion chamber. That turbulence improves flame travel for a more efficient burn and reduced detonation. Pistons are available to achieve various compression ratios. Features and benefits include: • Machined with a stock bolt pattern • Larger, more open combustion chamber presents less resistance to air flow around the valves • 2.000" intake valves and 1.605" exhaust valves • Special “cast to shape” intake ports with a special directional fin for improved air flow • Precision CNC machined from heat treated aircraft quality aluminum castings • Complete head assembly with valves and S&S .640" lift springs
