Probably you'll have some bent exhaust valves.  Unless the engine was
really revving when the belt broke, there probably won't be too much
more damage.  The intake valves are relatively small and tend not to get
hit.
However I would worry a bit about other damage besides valves, i.e. make
sure that the camshaft itself isn't damaged and also check the bearings,
especially the front one.

The engine should be the same; there was a change in 1994 but if both of
the cars are 1993 then you should be OK.  Make sure that the 100 does
not have a 1992 build date; make sure that it doesn't have a CO
adjustment screw on the MAF sensor.  If it does, you'll need to take
some more stuff off of the '93. 
Oh yea, if you're interested in selling some parts off the 100's engine
(or the 90), let me know :)
