I wouldnt worry about anything under 220* I used to race stock cars and cooling was always an issue I would come off the track at 260* after every race and once at 280* with no damage but you can Double check your Ignition timming make sure it's not too far in retard it's better to have more advance than factory but not retard.
Also you may want to underdrive your water pump to slow the coolent flow down. Onk was having a bad over heating problem and we closed off some of the flow with a nickle size washer he still has a cooling problem but it's not as bad he also has a high flow water pump I have suguested to him to put a stocker back in.
I have to agree with billy here, I was once told that although a rig should generally run somewhere about 200, if it tends to warm up getting around 220-230 isn't that bad. Maybe on aluminum engine might be a worry but on old cast blocks and heads I wouldn't worry.
I beleive mine got up over 230+ a couple times doing the burn outs a few years ago with no problems.
I have always felt that getting it that hot isn't that bad as long as you know why it is getting hot and that you can control it and cool it down when needed. If your just driving along and you r rig is getting that hot for no reason and you can't get it to cool off by slowing down or not putting such a load on it then I might be worried
