Autolite #85 for sure. Champions, in the experience of myself and so many others on this list, tend to ping and foul, causing the engine to run hotter. My vintage Mopars run on nothing else, and they all run well, don't ping, and never foul their plugs! (And my '78 NYB always passes Smog Check in CA like a new car, which is amazing considering it wasn't available here as a new car with the 400 like mine.)
