I have grown to hate the early small block accesories set up for reasons such as this. Setting up headers can be a challenge too. Most small block short sytle water pumps have a fitting at the top. A simple fix can be made with cast iron plumbing parts.
Use a 3/4" threaded adapter (threads at both sides) and install this piece into the top outlet. Then install a 3/4" x 1/2" 90 degree elbow to the adapter and finish with a 1/2" piece that is 2 1/2" long and exiting to the passenger side.
Mount the elbow flush with the water pump and paint to match (requires trimming the 3/4" adapter to fit). The 5/8" hose will slide over the 1/2" pipe threaded section and exit cleanly to the passenger side where the hose is routed to.
All these pieces can be found at a hardware store for about $2.50. Not factory, but a neat install. Some may call this ******* but it is a cheap fix. If you want show quality, these parts are available in stainless steel from a few differant companies found on the internet.
Good Luck!!
