After we tore down the top end I took a look at push rods. They look good but Im sure I read somewhere that a properly adjusted rod should not be able to be turned by hand. Some I could, some I couldnt. My buddy said it was because some of the valves were open and some were closed, which made sence to me. Does this sound right? Also I have FMS 1.6 RR, are these adjustable or are they simply bolt on and tighten down?
