Confused what to do with a 5.9L serpentine setup

Old rule of thumb: If you modify (custom valve covers included) anything during a build, you will have to modify 5 more things to make that one work. Looks like that still holds true.
I used the Mopar Performance valve covers and I guess that is why it has the notch in the corner.
Stay after it, it will come together.
There use to be a magazine called "Fun with mechanics". I have often questioned that while during Builds:)
