Default Bad Timing Belt Means Bad Top End

Timing belt went the other day and it seems I bent a few valves. Did not think this was a interference motor

Well , funny thing I have noticed on the valve thing. Up until now, and we'll see how this is. It's been someone having it done by someone else that runs into the bent valves. One reported bent valves in every cylinder. Just not even possible. So I'm curious to see how this turns out.

Here's a question. With the timing belt broke, shouldn't someone be able to pop the valve cover, rotate the cams so the valves are close on a cylinder and then do a compression test or at least a leak down test? And if you did that on all four cylinders and they checked out good, wouldn't that mean that the valves are not bent?

Seems like someone could do this before they pull the head for a valve job they very well may not need. But again, I'm not that familiar with these funny little cylinder heads.

Sounds like a good possibility to me. But as you stated not familiar with cylinder heads too much either.

They can't hit each other and they can't hit the piston.
It's impossible to just 'look' at an engine and say valves are bent: they are FOS
