Warming it won't change the numbers that much. It sounds like to me that you're numbers are really high, especially for a high performance motor. I've got my motor set up pretty loose, with a small ring package, and I've been told anything above 9-10% is too much. I ran a warm compression check the other day and my motor was down about 20-30psi across the cylinders from when the motor was fresh. I didn't do a leakdown though to see where I am loosing the compression. My suspicions are the rings though. I really need to get out and buy myself a leakdown guage.
