could be worth getting hold of a torque wrench - you may be really lucky and not done them up enough!

Most expansion tanks are vented, so don't worry about the hole in the cap (I can only think of a couple of models of cars which have pressurised tanks, no bikes.)

Suspect your various bouts of overheating have warped the head again

Skim it (get the top of the barrel checked as well), new gasket, torque wrench, re-check nuts frequently in first few miles.
