If you ordered the thin aluminum timing cover from HH you’ll end up with plenty of room between the timing cover and water pump (although you’ll lose the mounting boss for the fuel pump). The HH timing cover is designed to use with the short BB Chevy water pump and it looks like you have the long pump on the engine. It’s no big deal except the lower pulleys they sell to go with short pump and are too far in to work with LWP.
I had to use the short water pump, cover and pulleys on the 57 Plymouth to get fan clearance. On the 37 Dodge, I’m using the stock cover, factory BB LWP (which just clears the stock timing cover), and a stock BB MOPAR 4 grove lower pulley. I’ve still got to get around and figure out PS brackets for the 37.
