I'm halfway through my 5-1 exhaust manifold conversion on my CQ20V and found a head stud already broken. It has snapped about 3mm inside the head on the 5th cyl (top most stud). Has anybody got any advice as to how to get it out? I'm going shopping in the morning to see can i find any tools for the job but any BTDT's would be great.

Two other points of possible interest,
The head already has three threaded bores on each cyl not two like a 7A should have
The stud that snapped was already cracked; the break was black and sooty not clean metal so it’s given way a long time ago.
I pulled a stud from my spare ABY head to find the same stud snapped instantly and was black and sooty also. On closer inspection the gasket was actually leaking as a result. ....bit a trend forming here...
I also noticed the ABY manifold also has a large crack after the 5th cyl where the pipe bends. May have been a result of the above though.
