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!
