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

Part #: 900-0344

These S&S (R) Super Stock (R) high performance cylinder heads are designed specifically for S&S (R) T-Series T2 long block engines for 2007-'16 HD (R) big twins and 2007-'16 engines with S&S (R) 4-1/4" bore Hot Set Up Kit installed. 2.000" intake and 1.605" exhaust valves coupled with S&S (R) ports, supply plenty of air for these big motors. Not machined for S&S (R) 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 (R) High performance valve springs allow the installation of camshafts with up to .650" lift. Compatible with stock rocker boxes, exhaust, and intake manifolds.
