S&S Cycle 2006 Dyna Super Stock 91cc Cylinder Heads - Silver

These S&S® Super Stock® high performance cylinder heads are designed specifically for S&S® T-Series T2 long block engines for 2007-'16 HD® big twins and 2007-'16 engines with S&S® 4-1/4" bore Hot Set Up Kit installed. 2.000" intake and 1.605" exhaust valves coupled with S&S® ports, supply plenty of air for these big motors. Not machined for S&S® compression releases. The manifold mounting surface is machined to stock dimensions, so a special manifold/throttle body is required for engines that are not stock height. S&S® High performance valve springs allow the installation of camshafts with up to .650" lift. Compatible with stock rocker boxes, exhaust, and intake manifolds.

• Silver powder coat finish matches stock silver engine components
