is this too hot for my flathead?

[jhaas63]

Like most parts of the country, it is terribly hot here in Wisconsin. It has been in the lower 90's with a ton of humidity. I just installed mechanical water temp gauges on my 1953 8rt in my 53 f100. On a recent trip of about 20 miles, i noticed the temp was just over 200. When I got it to my house, the overflow was dripping a few drops but nothing significant. Any cause for concern here?
