S&S Super Stock Cylinder Heads For Harley Twin Cam

S&S Cycle 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 Twinkie, adjustable pushrods are a great (but not absolutely necessary) addition to whatever package you’re putting together. Don’t forget gaskets!
