Save the old head if you still have it. A broken tap can be removed by a
process called disintegration. It's similar to Electronic Discharge
Machining, but can be done in open air rather than under oil since the
finished job doesn't have to be pretty. They use a carbon electrode and an
electric arc to burn out the tap without damaging the casting. Shouldn't
cost more than $25 tops, maybe less.
