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.
