S&S Cycle 90-1106 - S&S Cycle 89 CC Super Stock Cylinder Heads For Harley Davidson FLHR 1450 19

Features: Heads are fully assembled with springs and valves. Designed for '99-'05 engines with stock crankcase. Good for touring bikes and other heavy vehicles. Works well with stock displacement, but are ideal for somewhat larger stroker or big bore engines up to 110". Combustion chamber provides a slightly higher than stock, but still manageable compression ratio in larger than stock engines. Large 2.000" intake and 1.605" exhaust valves maintain port velocity for good low and midrange response, but supply enough air for slightly larger engines to perform to their full potential. S&S® High performance valve springs allow the installation of camshafts with up to .650" lift. Intake ports flow 264 CFM (Cubic Feet per Minute) compared to stock heads at 182 CFM. Compatible with stock rocker boxes, exhaust, and intake manifolds. Made in the USA. Must use S&S rocker boxes if S&S compression releases are used..
