I found that there is a 5/8" barbed heater core nipple underneath the oil filter.  I had originally figured on using that to go to the heater core. There is another area for a fitting on the water pump. It is an angled fitting right next to the very bottom of the water pump where the large -16 hose will connect. See area labeled "connection 2" on the picture of the water pump. I had planned on using that for the other connection to the heater core. Finally, there is also another plug on the water pump labeled "connection 1" in the same picture. I have no idea what that is/was for.  Any suggestions on how to incorporate a heater core and this expansion tank into my system?   
 
 I believe the barb you are referring to was actually a coolant line plumbing to the intake manifold instead of the heater.  The heater outlet is on the spark plug side of the engine.

Hi, Ed....The barb on my engine, which is under the oil filter, is right next to the spark plug.  On my engine, the oil filter and the spark plugs are both on the same side.  Thanks for the input.  Thanks to Lynn, Rusty, Al. John, Ed  and others I think I can do this !!! (I hope I didn't miss anyone who contributed) Thanks to everyone for helping me to understand the workings of the system....then it's easier to plumb.  Paul Conner
 
Sorry, you'r right, Paul.
 
    I should have noticed the size you mentioned, that is the heater core coolant outlet.  The one I erronously thought you were referring to is approx 1/4" dia and on the same side as  where the oil injectors are mounted.
