Those numbers aren't too bad. Did you re-check the one that was 165 to make sure if wasn't a false reading the first time? How many cranks are you letting it go and are you holding the gas pedal to the floor?

I would put in some new plugs and drive the car for a bit and see how the plugs look after a day or two with the wires switched around. Your compression isn't low enough or that different from 1 cylinder to the next for it to be that causing the problem. Maybe pull your valve cover off also and make sure nothing popped off up there.
