Get a left hand machining grade drill bit (shouldn't be more than $10) that is slightly larger than the old bolt, drill it out, then tap it for an oversize bolt. You will have to drill the manifold for that one bolt as well, but DON'T tap the manifold!! I hope that you know that already... But double check to be sure that drilling it larger won't stress your head, some will and some won't... Looking good though! (minus the cussing...). Keep it up!

If I can't get the rest of the bolt out of the threads I was actually thinking about using a slightly thinner exhaust bolt with an extra 1/2" of threads and using a nut on the backside to fasten down the manifold... It's on the the middle exhaust port so I don't think it will leak...
Opinions on this? It would save me quite a bit of time but I don't want to do anythingthat will just need to be redone later.

That might work. But personally I would drill it out, either tap for a larger bolt, or put a heli-coil in. Ask a local machine. Shop what they think! Usually they know all the ins and outs of those stuck bolts. If you can post looking down at the head where u want to put the nut, that would be great!

I suggest using a Heli-Coil or similar thread insert. Just drill out the remainings of the old bolt, tap the hole for insert and screw it in. Much cleaner looking than tapping it over size thread and using bigger bolt.
Just the other day I fixed broken alternator mount with Time-Serts (similar to Heli-Coil), and two threads took time about 15-20 minutes.

Well I got the motor and trans bolted together. I have been deciding the best place for trans to sit for shift linkage. I am putting together some cardboard mounts to mock up as motor mounts. I have a buddy with a drill press and a plasma cutter. I'll be using the liquid filled mounts. Probably back/center mounts on the passenger side, still haven't figured the best block location yet due to the starter and extra oil fill location(which I'm hoping to delete with my mount and a gasket.
I should be getting Internet back soon and I will add more pics. Too time consuming to photobucket from the phone
