Try an easy out, they always work for me. Any auto parts store should carry them or harbour freight.

Grind or file the bolts ABSOLUTELY FLAT; mark them carefully in the EXACT CENTER with a center punch; drill STRAIGHT into them with a small bit, like a 1/16"; re-drill with successively larger bits until the remains of the bolt come out; finish with the bit for a Heli-Coil of that size (will take a 25/64" bit", Heli-Coil them, and put back together with STAINLESS STEEL bolts.
No need for replacing the manifold. Especially since there's no "direct" "replacement" available except a junk one which is equally likely to have the EXACT SAME problem.

Yes it will work for both.
drill a small hole in the center insert easy out and turn till it comes out.(use heat if needed)

Best to drill and pick out the remaining bolt or use a reverse turn drill bit that grabs the last bolt parts out....When the easy-out snaps off you will add 2 extra hours tryin to get the hardened metal out....

Re: big trouble! any ideas?
Avoid EZ-Outs... about 99.999% of the time they break off, and then you have a REAL mess on your hands, because they're ALOT harder to drill than a bolt.
Drill it. Don't try the other.

Re: big trouble! any ideas?
I usually go the drill out route too if access isn't an issue but I've also heard you can weld another bolt on top of the sheared off bolt. Might have the same issue if it's still really seized but it may be another option.

Correction. Not another bolt. A nut and weld inside it to the sheared off bolt.

Re: big trouble! any ideas?
And use anti sieze on the new bolts before you put them in!!!

Re: big trouble! any ideas?
There's been many times where I couldn't get a bolt off with channel locks or a vice, but I like to always keep a pipe wrench handy because the way it gets tighter as you turn it, has always worked for me on any occasion.
