broken exhaust manifold bolts

Anyone have any good tips for removing broken exhaust manifold bolts? They are on a 2001 6.0L. Looks like everything says they are 8mm but a 8mm socket doesn't seem to fit to get the non broken ones out with.

Weld nuts on the broken stud. It will be a bitch to get out. I just paid some serious coin to have mine fixed. 4 broken off, 2 new manifolds and right side pipe. Piss poor design, just make sure to get the updated manifolds if you are not resurfacing yours.

When I did them I just warmed the engine to operating temp to soften the threadlocker, loosened all of the remaining bolts with heads, pulled the manifold and drilled / easy outed the broken ones. I purchased the new updated bolts and gaskets from the dealer and installed them. I was told that they are now either heat treating the fasteners differently or they have changed the grade of the bolts to allow for the shrinking and expansion of the manifolds. It wasn't half bad.
