Here is the latest update:

Pulled the radiator and brought it to the local shop. They are looking into it. In the mean time, I am flushing the block. Have the driver side soaking in some rust kill/simple green. Ran out of time yesterday to get the passenger side soaking. Will drain the driver side this weekend, pull the water pumps and flush with a water hose and start the passenger side soak. I also have the Greyhound cap rebuilt with a kit from Mac's. It looks like a much better set up than the one I had.

I have emailed Skip to see about his 3lb overflow check valve but have not heard back yet. will probably have to call him.

After reading FlatFord8's post I'm going to take a look at my plug wires and make sure I don't have any crossed up as far as firing order.

Once I get the radiator back, I'll put it all back together and run it and see what happens.
