One of the problems with the 13b water pump (cut down or not) is that the intake and outflow from the pump do not head in a 'helpful' directions to route coolant hoses if the radiator is mounted beneath the engine.  I am not very satisfied with the solution I came up with the first time around, so I am pondering some rework while I reinstall the engine next weekend.
First thought is to weld a 180 bend onto the pump as shown in the figure.  This makes it relatively straight forward to add some hose + a 90 degree bend to get to one side of the radiator.  But it does nothing to help getting from the goofy 45-degree pump port to the other side of the radiator.

Anyone have a better idea how best to lay this out?

Here is what I have come up with but it requires a two pass rad.
