Just tested my b16 and got:
187 1
175 2
190 3
193 4
Kinda overheated once because the lower radiator hose was leaking but hasn't burned any coolant, no coolant in oil, doesn't seem to smoke and runs well since i fixed the leak.

Are the comp numbers anything to worry about because the difference between highest and lowest seem to be within spec?

 

To me, that is right on the border of a concern. I would do the test again after adjusting valve lash and then warm the engine up. If #2 was still low, I would do a leak down to check. As long as things aren't any worse with the engine warm or the leak down saying there is a serious concern, I would send it and plan to pull head at some point in the distant future to check the cylinder walls and lap the valves.
