By removing everything, drilling out the broken bolt pieces and fixing the threads with a helicoil. It will probably take a remote drill head ( either flexible shaft or 90º adapter to get into the confined area. That's the only way I know of without removing the head. I've done it, it works.......time consuming and close quarters though.

Jeff has the right idea. I'll get a pic of the tool I'm gonna use. Should make easy work of it without harming the threads. The Takes about 2" of room. Right angle drill, really small.Originally posted by Joe 1320

That bolt is famous for being broken. Good luck removing it, I was never able to find a tool that could fit in such a small area. That is why I ended up getting the SLP headers that use a different (unused) bolt hole. My broken bolt is still in the head. Are you sure your headers use the same bolt battern as the original manifold, some/many(?) don't?
