The 165 is a hair low. Not terrible.
Driver side was 180 all across passenger side was a bit up and down.... just sent the carb off for a rebuild... I should get a couple more years with this compression? Not trying to open it up.

You will be fine

worst case is check the 165 cylinders plug so its not fouling out from oil

Was that one open? If so that could very well be your poor running issue. Yeah just plug them.
