I've always blocked off that hole with a small freeze plug(1/8 or 1/4?). Engine builder told me years ago it would reduce engine temp by 30 degrees because that hole shoots water on the #2 cylinder causing steam to build. Don't know the dynamics behind it, but it does work for me!!

Forgot to mention I block off the hole in the pump, not the block.

The aftermarket aluminum waterpump that I run, came from the factory with that hole plugged. So I say, yes that hole can safely be plugged.
