I am not sure how the oh valve system works. Are there four valves per cylinder operated by two separate cam shafts? Have suspected bent valves do to bad timing belt. Please answer.

Good afternoon.

If you feel you have bent valves from a failed timing belt, I would perform a compression test to verify.

Remove all the spark plugs and check the compression in each cylinder. They should be around 130-140.
