Description
S&S Big Twin Super Stock Cylinder Heads
S&S Super Stock cylinder heads have high flowing ports and a 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. Requires S&S Super Stock pistons, sold separately.

Larger, more open combustion chamber presents less resistance to air flow around the valves
2.000 inch intake valves and 1.605 inch 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
