Nuffield 4DM Cylinder head. I have only pressure washed the head (lightly oiled after) so you can see the face as is. Would as always recommend skimming. This head has nipples under the injector ports, could be for heater plugs but only small???? Have not removed valves. Will put the rear end plate with it. The last photo is of the engine block serial number, the head came off, 4DM. Please see my other Nuffield Items.
