Water Pumps / Cooling Systems

Hi All....
Are there different water pump configurations for a 2362 Deluxe Eight?
I pulled my old pump, and started to press it apart and noticed there was to retainer on the bearing. Also, there was no groove in the bearing sleeve. I checked the impeller clearance from the backplate. It was a good .015 over max. allowable spec. I ordered a new pump from Kanter, and it has the retainer and looks great. Was my old pump rebuilt with a different bearing, or did some not use the retainer? Also, the gasket for the new pump has a "cutout" from the small upper hole to a point on the pump body with no corresponding opening. This won't hurt anything. I'm' just curious. Further, I started working on the cooling system because of a "thinking" sound coming from the head, after a short run time. Sounded like a "hot spot". The sound occurred at about 30 second intervals. I have heard this once before on an old Ford flathead, I wound up rebuilding. It had a bad water pump. I had the head boiled out when I replaced a valve and keeper on the Packard. Also, I back flushed the block while the pump and thermostat were off. I am retrofitting with a new aluminum radiator, as the original was totally shot. I am unable to remove the copper water distribution sleeve from the block. It will not budge. We will see if the new pump and radiator get rid for the "tinking" sound. Any comments would be welcome.
Thanks a bunch,
