Why not have a bash yourself? You can't go far wrong with some drill bits and a tap especially on a cast iron head

Always an option I suppose. What's the plan? Use progressively larger bits until what's left in the threads can be picked out? I'm a bit worried I'll cock it up and have a useless head. I imaigne the plugs are pretty much part of the head now so will probably be a bugger to get out.
EDIT: As an aside, is the Ford TIS available on this forum somewhere?
