It was the C7 valves. But the heat in the muffler wasn't the only problem - if you recall, the piston sleeves had to be replaced as well. I remember when Julio took the first Tellurium-pistoned bike out for a ride, and the cylinder heads melted out from under him. What a surprised look on his face! Priceless. Actually, they reconfigured the paladium plugs so that it wasn't necessary to rebuild the engine with tellurium parts. (Besides, I'd rather go without mufflers than to replace those muffler bearings - what a job!)
On ANOTHER serious note, I usually just use NGK's. Unless it's in my car, then I'll get platinum tipped (because it says so in the manual, and the car doesn't run right without them). I've never had trouble with Champion plugs in a car, but I have a friend that has had trouble only with Champion plugs, and swears by Autolite. In any case, all the plug has to do is spark, and the fuel/air mixture does the rest. If you're worried about it, get higher powered coils so that you know you're getting a spark. Then it won't matter what plug you buy.
