I assume from your last reply that your rotor is not turning. Most likely the problem is with the distributor gear. A broken distributor gear should not result in any damage to the valve train. However there could be lots of crap from the broken gear inside the engine that has to be cleaned up.

If the timing chain has jumped a tooth or worse still, broken, you very well may have bent some valves and or push rods. If you think this could be your problem, remove the valve covers and check that all the valve stems (for those valves that are not open) are at exactly the same height. If any of them are down a bit, they are probably bent. If any are up a bit, they are probably broken. Also check all the push rods to make sure none of them are bent.

A compression test will confirm bent or broken valves as the compression on those cylinders will be zero. Be careful craking an engine too much, that has this type of damage as you could make things worse.
