Most of the water pumps came with a 5/8" outlet pipe. However some of the 1958 & 1959 intake manifolds had a 7/8" pipe instead of 5/8". The pumps would come with a rubber spacer to make up the difference. You can put a rubber spacer (smaller diameter hose) on the intake pipe and just use a 7/8" or even a 3/4" hose instead of modifying the pump.
