Need Help! Big Block electric water pump to engine plate information.

I use a 180 degree fitting as you have pictured and I also welded -20 aluminum weld bungs on my water pump, radiator and T-stat ends to use -20 upper and lower AN hoses with no issues. It is tight, but it all worked. I also use Meziere electric water pump on the street.
