Anyone using an electric water pump?

Your radiator guy is giving you bad advice, probably based upon advice he got from someone who didn't know better. As scottj pointed out in post #22: "The longer coolant is in the radiator, the longer it's in the block gaining heat." That's almost a direct quote from what Stewart Components includes in their cooling Tech Tip #3. Stewart Components

More content from the same Tech Tip:

• "We strongly recommend NEVER using a restrictor; they decrease coolant flow and ultimately inhibit cooling."
• "Coolant in the engine will actually boil away from critical heat areas within the cooling system if not forced through the cooling system at a sufficiently high velocity. This situation is a common cause of so-called "hot spots", which can lead to failures."
• "Years ago, cars used low pressure radiator caps with upright-style radiators. At high RPM, the water pump pressure would over come the
  radiator cap's rating and force coolant out, resulting in an overheated engine. Many enthusiasts mistakenly believed that these situations
  were caused because the coolant was flowing through the radiator so quickly, that it did not have time to cool."
