S&S Cycle 900-0470 S&S Cycle 99-05 BT Super Stock 91cc Cylinder Heads - Wrinkle Black

These S&S® Super Stock® high performance cylinder heads are designed specifically for late production S&S® T124 long block engines for 1999-'05 HD® big twins and 1999-'05 engines with S&S® 124" 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. The manifold mounting surface specially machined to compensate for the slighty taller 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. Wrinkle black poweder coat finish matches stock black engine components.
