Anybody use one of these water pumps?

Got a friend who has used them on his WISSOTA late model with good results... anyone else have an opinion?

Seems like this would eliminate the need for me to modify the pump and timing cover to improve the water flow by shimming the space between the timing cover and the impeller.
