Did you pull the valve covers to see if no valves were stuck, or just count on it binding up when turning over with the breaker bar?
I did not. I've only had stuck valves one time and I could feel that. But there's nothing wrong with pulling the covers and making sure. Sometimes you have to do things just to sleep well at night.
