93 integra ls-if the timing belt snaps,does it bend the valves, or are the pistons indented to allow for this?

 

Yes it can bend the valves :yes:

 

Depends on how lucky you are. Yes it *can* bend the valves, but then again, it may not.

I was told by a good friend who works in the service department for my local acura dealer that it was about a 60% chance of doing *some* damage.

I was lucky when I busted mine. No damage at all. I wish the same luck to you.
