You keep wanting a cylinder compression number?I assume you are having some problems .. Why don't you just run a leak down test, that will tell you if everything is sealed up correctly or not.. Last compression I ran was in the high 180's, that was a motor I had just rebuild, using SpeedPros' gapless rings , which will produce a bit more pressure.. Still, if I though I was having problems, I would run the leak down test, will give you a more accurate diagnosis...
