hi all,vaguely remember a way to change the stems seals without taking the head off.
get the piston to tdc,you then push suitable rope into the combustion chamber,this will stop the valve you are about to work on from moving downwards,then with the cams etc removed,with a forked lever and suitable pivot point you can compress the spring to remove collet etc to get to the seal,we used this method on a mates xr3 back in the distant 80's,dont know if it would work on the alfa,might be worth a shot,considering the amount of labour ,new gaskets etc to remove the head,cheer all.
