To update: I'm in the process of replacing the vario-cam pads. I started with the 1-3 bank as that was the one with the worst cam deviation. I'm doing it with the engine in the car. So far, not a real big deal. The most excitement was taking the header/cat off. I was sure that I was going to break off one or more bolts that attach the header to the head. 0 for 6 on breakage! Used a healthy dose of PB over the course of 24 hours and then used an impact driver. They all popped out intact. I'll replace with stainless steel and high temp anti-seize paste.
The indie that I originally talked to about the cam deviations wasn't too worried and suggested a wait and see approach. One pad was ok. The other was severely worn and crumbled when I pulled it off the vario-cam.
