generally don't look at the actual number, because it can vary between testers and motors, look at variation between cylinders, closer to each other the better, around 15% is probably still ok, but not much more.
I think the manual says its around 160 for a stock 26 and gives a tolerance.
For example my RB26 is rebuilt and it seems its used lower comp pistons (i dont know why you want this but i didnt build the motor bought like this) but was 120-125 across all cylinders. Also blowing a dip stick out isnt a good sign and PCV isnt working at full throttle only light cruise...
