Hi Pete,
This is why most experts recommend leaving these alone if you 
can.  Personally, I ignore this good advice and remove them and install 
TimeSerts.  Ray Sedman and TimeSert have slightly longer TimeSerts that are 
perfect for this, but I have had good luck with the stock ones, that I 
believe are 3/4 inch long.  To remove the stud end once broken off 
typically requires using a torch.  This is tricky, since an OxyAcetylene 
torch can melt the aluminum.  Maybe you will have good luck with a propane 
torch and a stud remover.  Also you could weld a nut to the end of the stud 
and that might help.  I would try that approach.

If you try TimeSerts, make very sure you take a die to thread chase the 
interference threads of a stock head stud.  Otherwise it will bind up in 
the newly installed Timesert and rip it out.  I can personally guarantee 
this will happen and then you might have toasted the entire block.  If you 
chase the threads, you will go through dies quickly, but once done, you can 
relatively easily replace head studs.  I use Loctite to lock the studs once 
installed.

Good luck with this.
