180+. 200 = real healthy

165 = rebuild time

i editted that but it didnt show up

200+ is healthy, but did you check it with the throttle open? cause you should hold the pedal to the floor while you crank it. Your numbers will be much higher if you allow the engine to breathe

aftermarket (or re-ground) cams reduce cylinder pressure also.

Ive got about 170 in all four.

Just boost it, it will love it and last forever.
