S&S Cycle Cylinder Heads For Harley Big Twin Evo

Bolt on some ground-poundin' power. These heads are designed to be used with stock flat top 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!

Features:

  • Kits are fully assembled, and include stainless steel valves and high-lift (.585") springs
  • Optimized for smaller displacement engines
  • Slight increase in compression (8.8:1 in an 80" motor) with 82cc chamber volume
  • Port design increases flow while maintaining velocity
  • Set up for .585" maximum lift
  • EFI compatible
  • Available in silver powder-coat or black powder-coat finish
  • Sold in pairs
  • Made in the USA

Do they make this for 1200 sportster?
A C on Feb 9, 2017
Are s&s heads better than Harley Davidson?
A shopper on Jun 13, 2016
Though they appear to be about the same design/color as the original heads I thought it best to ask to be sure, is the coloring the same as what I presently have on my '99 EVO, black powder coated with silver on the fin edges? Thanks......
