These S&S® Super Stock® high performance cylinder heads are designed specifically for late production S&S® T111 long block engines for 1999-'05 HD® big twins. 2.000" intake and 1.605" exhaust valves coupled with S&S® ports, supply plenty of air for these big motors. The manifold mounting surface specially machined to compensate for the slighty shorter cylinders, so a stock length manifold/throttle body will fit. 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.
