No way of knowing without opening it up. The fun you get overrevving your engine is huge . You lost compression in cilinder two, the resason why is to be determined.

Did the car overheat on you at some point? When did you notice the misfire happening? Cylinder 2 compression is low, I am wondering why you are getting misfires for 1 and 3. Have you changed your spark plug wires, distributor cap and rotor? Check to see if there is spark at each spark plug wire. If all this checks out then next thing will be to remove the head and inspect the valves and valve stem seals.
