S&S Super Stock Cylinder Heads For Harley Twin Cam

Bolt on some ground-poundin' power. These heads are designed to be used with stock flat top or aftermarket pistons. You don't need crazy-master-engine-builder-status to make good, usable power - just bolt them in and go.  While they will work with stock components, a good exhaust, air cleaner, and cam will make these heads really shine. (You can go a little wilder with the cam, too - S&S installs high-lift springs for you!) As with most engine modifications on a Blockhead, adjustable pushrods are a great (but not absolutely necessary) addition to whatever package you're putting together. Don't forget gaskets!


  • High port flow gives great performance now, and more later when additional upgrades are done
  • Heads are fully assembled with springs and valves, and are available in silver or wrinkle black powder-coat
  • Compression ratios vary depending on cylinder heads chosen, pistons used and engine displacement
  • 79cc heads work great with stock motors for 88" to 103" motors
  • 1.940" intake and 1.575" exhaust valve and springs for up to .640" lift
  • Heads accept OEM rocker boxes
  • Heads are machined for compression releases (sold separately); S&S rocker boxes required when using S&S compression releases
  • Do not include rocker arm components, intake manifold, gaskets or head bolts (requires eight long OEM length head bolts)
  • Accept OEM intake manifolds
  • Sold in pairs
  • Made in the USA

Fitment Notes & Exceptions

  • It is the responsibility of the installer to check and re-check all clearances when installing these heads
