These can be quite difficult for getting all of the air outside the cooling system. As far as I know when a head gasket goes on an XUD (or DW8 for the matter) its quite dramatic and I don't believe it has repaired itself by any chance.
Also, the electric earth issues can cause all kinds of a erroneous temp readings on the gauge. Just to be sure, connect additional ground wire from the negative terminal of the battery to position that is close to the temp sensor for the gauge. At least you will know the temp indicated is not influenced by the voltage drops on the earth system.
