Would the water pump rotation matter for the engine I bought?

If not then should I just start searching Rockauto for c10 to c1500 trucks from 1973 to 2002 and see if I can find a long style pump with 2 ports in it, not unlike the one I started this thread question with? I wasnt sure if the long style press on fitting stems in that one could be removed and hopefully get some NPT barb fittings to replace it. Maybe Rocknrod was saying that the fittings are pressed into the pup and have no threading?
