Norton Cylinder Head Issues:

We all know with some original cylinder heads  there were problems with porosity, to porous castings which can lead to oil leaks and poor balance between cylinders.  Stripped exhaust port threads another, broken fins, or disfigurement from misguided modifications over the last 40+ years of rebuilds.

Fullauto technologies re-engineered cylinder heads for Norton Commandos

Made from virgin 601-T6 Aluminum. 

These are not a copy of the original, these are a significant improvement.

Whilst these heads were not designed to be a performance part they are a vast improvement to the original, with looks that are very close to all but a purist.

D-shaped exhaust ports and long raduis inlets improves gas flow.
