Not really a good way to test it with the timing belt off aside from removing the head. All that head removal adds to a timing belt is an hour, a new set of head bolts, and a new gasket.

An EX has an interference motor, so technically, if you were traveling at a high rate of speed and it broke while your car is in gear, they're probably bent. Just cranking your starter if the timing belt is broken will usually result in bent valves.
