I have used Evapo-Rust extensively with excellent results.
However, I have not used it on the coolant passages of an engine block or in a radiator.

Have you flushed the cooling system? If so is it clean and does it flow well?
The manual lists the radiator for the Six as having "Gravity flow new, 38 to 41 gallons per minute."
Have you measured how hot it is when you say it "has a tendency to run hot in traffic and at idle."? The thermostat you put in was the correct 147 degree based on the part number.
You haven't described it as hot enough to boil over.
