BlackEagle, I would say that the MD-15 is definitely the pump you want out of those three.

Unless you have a very specific need for the higher pressure pumps like the 20/30-RZ models, you will be worse off with them. Too much heat/noise for little real benefit at the block, and a net loss once the radiator has to try to remove that heat.

I'm somewhat familiar with the heater-core you're looking at and it is a "rough" equivalent to a single one of the cores that I use in terms of cooling performance, based on the experience of one person I know who has had both in a setup and switched between the two.
