Dave;

I'll run it again to see if I can tell if there is much difference in the compression. As I stated, it seems to be running cooler now than before but I don't know how cool/hot it should be - certainly very hot to touch after running on the ground. My little DURATRACK temp gauge tells me it was almost 200F and the RPM would drop but it now holds the rpm and stays at about 150F-175F on the head near the exhaust. I don't think I changed the NV O-ring so I'll change that next too.
