A simple head only package of Alfaholics upgrade components for Nord engines of all sizes – 1300/1600/1750/2000.

The kit comprises our hollow billet cams in mild fast road profile, performance valve springs, DLC cam followers, GTA curved rampipes and gaskets to rebuild and install the head. +15BHP on its own or +25BHP when fitted in conjunction with our full s/s sports exhaust which we strongly recommend to get the most out of the package.
