Magnum serpentine pulleys with LA timing cover?

That’s the stamp on the crank pulley. I shimmed it 1/4” and it lines up perfect with the water pump pulley. I bolted on my alternator with the same shims as my last engine and it lines up perfect with the water pump pulley. The power steering pump is also off about the same as the water pump pulley so the crank pulley is definitely the culprit
