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.

These super stock heads are a beautiful set of heads. Top notch American made products from S&S. Wish the matching pistons and cylinder's were available sooner, worth the wait though.

Without knowing exactly what bike you're putting it on, or the overall state of tune that bike happens to be in, it's hard to say exactly how much extra power you'd get out of these heads. What we can tell you is S&S claims that, when using a stock cam - you can get at least another 10 horsepower out of the engine, so long as you also use the required S&S Superstock pistons.
