Should cloches have an air gap top prevent over heating. I use them, as I am on a south-facing slope and my garden is usually a month behind others in the same area since my soil is colder. I made mine in an "A" frame shape, as I had some "Polygal" sheets rescued from the tip. They are opaque, not clear. Would this affect the sunlight entry too much?

That should be fine, and yes, if using this material, I would add a small vent in the top. For additional information on using cloches, this article should help: https://www.gardeningknowhow.com/garden-how-to/tools/using-cloches-in-gardens.htm
