Twin cam timing belts (That's what stuck, the cam shaft) are a PITA to put on and time correctly at times. A single tooth off can stop a car from starting, and they often float 1/2 tooth under normal use... so that gives you an idea of the tolerance for error.

According to what I remember, your engine is a non-interference type, which means that unless something inside the engine let loose, the pistons CAN'T make contact w/ the valves. The only other way you could have bent a valve is to bend the stem, which is also highly unlikely, but could happen at high RPM when valve float becomes an issue. I'm sure you weren't cruising at 10k RPM, though.
