In that case it may be possible to sort out with the head on, but it'll not be easy if the studs have snapped flush, or sub-flush with the head alloy.
'Easy-out' type stud removers can work, but it is critical to drill the pilot hole really central. They have been known to snap off compounding the problem.
I had just the very front one go on ours (immediately adjacent to the thermostat housing). Eventually got it out with the aid of a very short electric drill and a special jig I made to ensure that the drill stayed on course. T'was a struggle, but very satisfying to solve.
Tried easy-outs but gave up as I could 'feel' that I was about to snap one. Re-tapping my newly opened hole was a delicate business too.
Jig available for loan, FOC; but IIRC it sits over the nearest other two studs, so you might have to remove/replace the other bust one before it could be of use. :)

If you can get some round bar which is a tight fit in the manifold bolt hole you can drill a 2mm (say) hole through it and use it as a drill guide.
You will need a good light and a mirror to centre the manifold hole on the broken stud (quite a bit of slop in the holes) then nip up a couple of nuts to hold it still. Insert the drilled rod and use it to drill a pilot hole in the broken stud. Be very carefull not to drill too deep, just through the stud and no more, as there is a water jacket behind the front stud.
Biggest problem you will have is getting a drill in there, space is tight, a 90degree drive might be necessary.
If the studs were already snapped then check that someone hasnt already tried to drill them out....
