If I remember correctly that's what I had recorded on my radiator also before the rust flakes blocked some tube tops. I run a thermostate (175* I think it was) and I had about 180* on the top tank and about 140 on the bottom tank. The top half of the radiator should loose a little more heat than the bottom half because the teperature differential of the air to coolant is greater on the top half. That's also why modern cars can get by with smaller radiators; they run hotter, so it's easier to shed the heat.
