Question about Ford Cars & Trucks
With the exhaust manifold off. If there is some of the bolt sticking out. You'll need a torch to heat the head up, red hot around the bolt. Also a pair of needle nose vise grips to grab it with and turn it out. You'll have to heat it several times to get out. No bolt showing, you best bet it to pull the head. Drill the bolt and extract it.

Get a smaller bolt and clean the area with a wire brush and weld the smaller bolt to the broken stud careful not to weld stud to head with the smaller bolt welded should be able to remove broken stud with a wrench or vice grip or rent or buy a right angle drill and drill onto broken stud and use heat and an extractor to remove ---lastly if to tight to do either unbolt head and work on bench to remove stud

Very limited options for this repair
it will require room to operate the necessary tools for drilling and extraction and that may mean the removal of all items in the way
discuss any options with an engineering engine repair shop ( not the local corner garage) as you will need specialized skill to effect removal of the broken stud and refurbishment of the thread

Whatever it takes, but make sure you soak some penetrating oil oi wd40 on others to avoid any more being broken. Pulling the manifold is the safest and quickest way. With it out of the way, you'll have someting on the broken bots, now studs to work with. Always drill a broken stud or bolt clean through. Penetrating oil can work from both ends and a broken easy out can be driven in far enough to work arounf -Good Luck, force nothing, Tap stud and apply only stesdy even presure when extracting.

These bolts usually have become very hard and brittle from the high temperatures. You will need carbide drill bits to drill into the bolt remains for insertion of an 'easy-out' tool. 'Penetrating oil' squirted into the threads may help remove the ends.

If it's broken off below the surface you'll have to drill the remainder of the bolt out. If it's broken off above the surface and you're somewhat handy you can weld a nut on the end of the broken stud and remove with a socket wrench. Here's an excellent read on the how to of removing broken studs....it saves me the time of having to type it all out. Good luck.
