Does the motor turn over when it is cranked?

I had a similar situation happen to me, and I think it ended up being a bent valve. Ever since my vehicle rolled back in gear, I have a "misfire". So far the fueling system has been eliminated, which only leaves either the head (valves??) or the piston rings that has collapsed.
