I find that it is tough, but easier in the long run, to just pull that piece down a 
little bit and insert the thermostat from the rear/below.

If it weren't for bad luck you'd have no luck at all!

I'm paranoid about this, so I always stuff a rag or paper towel in those holes 
any time they get opened up. They're just too inviting.

At least the spring was there (it was, wasn't it?) so that the flaps were still 
open.

Yes, that's a very tough job!

Just leave them for now. A good machine shop can fix them the next time 
you need a valve job. The rear end of that cover tin is secured around the fan 
housing outlet, and the front end by the lower tin. An Easy Out will just make 
you miserable and leave a piece of hardened steel stuck in there. The only 
way to remove these is to drill them out, and this is best done in a place 
where the drilling angle can be controlled and held steady and straight.
