8.1 Workhorse exhaust bolt broken

[Ready2BRetired]

Have an 8.1 in an 05 Tiffin. Rear most pass side exhaust bolt broken below the mating surface. Any ideas w/o removing the head? Possibly have room to drill and tap not sure. Anyone ever use the KRAL brackets instead of removing the bolt? Open to all suggestions. Really don't want to remove the manifold itself as I believe I would end up with several more broken.

I have heard that the kral or dorman brackets work well if the gasket is not blown completely out. I would like to put them on my 6.0l as a preventative.

Bolt is broken below the surface, no chance of grabbing it with anything. Leaks only on start up for about 2-3 secs then is fine. Don't know how long that will last though.

Is the bolt flush with the manifold? It's going to be difficult with the manifold in place. Is the gasket leaking? Any cracks maybe best to remove or replace the manifold?
