To avoid this and keep the passages clean I am thinking of routing a 5/8-inch hose from each back corner to the front corners of the intake manifold. Perhaps I am getting an air bubble which is blocking the coolant from circulating?

Does anyone see a problem with this? Would this decrease coolant flow through the heads?

If you have a better idea please let me know what it is.
Yes, it has been done before. I've seen it.

The Air-Gap uses these passages that could be used for that (As you mentioned)
