Description

• Product

• • Heads are fully assembled with springs and valves
  • Designed for stock 88″ to 103″ engines or slightly modified engines up to 110″
  • Moderately sized 1.940″ intake and 1.575″ exhaust valves maintain port velocity in smaller displacement engines for good low and midrange response
  • S&S® High performance valve springs allow the installation of camshafts with up to .650″ lift
  • Combustion chamber provides a significantly higher than stock, but still manageable compression ratio
  • Heads can be decked up to .060″ to increase compression, but will require piston valve pockets to be re-machined
  • Compatible with stock rocker boxes, exhaust, and intake manifolds
  • Machined for S&S® electric or manual compression releases
  • Made in the USA

  • Not compatible with ’14-’16 FLHTK/FLHTKL, FLHTCUTG Twin-Cooled motors or ’17 touring models.
  • Must use the included S&S valve cover gasket kit with stock rocker covers.
  • Must use S&S rocker boxes if S&S compression releases are used.
