The same happened to me, but after I replaced my belt, the engine turned over and started fine, it even idled good! But the car did not run too good though. I had to advance the timing all the way, so I could drive it to my garage. I'm in the process of taking the head out, I'm pretty sure that a lot of the valve are bent.
The same might have happened to your valves, only worse. Enough where the engine doesn't start, because of very low compression...
