put a new exhaust cam in

So I just put a new exhaust cam in my b16 and I checked the adjustment of the valves they were good and set the timing now it wont start.
If one or more of the valves is bent will that keep it from starting?
I need help becuase i dont know what to do anymore i can hear the starter and see the cams turn when i turn the key but it wont turn over any help?? please?
