Here is another photo of the back of my water pump when I removed it. You can see that the hole in the gasket and backplate are in the same position as the block.
Also, referencing the comment by TxGoat, In some cases the hole doesn’t have anything to do with the coolant flow with a thermostat closed. For example, my car being a 138CD, there was never a thermostat at the block to limit coolant flow. Instead, my car used a thermostat in the radiator to limit air flow that opened the grill louvers. There was no thermostat to limit coolant flow. For the 1937 120 line, the CDs got “upgraded” with the thermostat for the grill louvers.
