Solutions for too much compression

I think you have something seriously wrong in your measurements. Either the compression ratio is much higher, or the cam is out of time, or the timing mark is wrong. You ARE running decent fuel, right? How hot does it run?

I am about to try to double check the basic cam timing as well as I can without taking the front of the motor apart. Yes, premium gas only. The motor runs cool enough. Around 190 degrees. I checked the timing mark on my balancer and verified it is pretty darn close, if not dead on.
