ALL aluminum valve covers need to be clearanced where they butt up to the intake manifold.

There should be a knockout hole on the opposite end of the valve cover from the screw-on cap (look on the underside of the cover). A stock Mopar PVC can be used there along with a standard Mopar screw-on cap on that valve cover, and a standard screw-on oil breather cap on the opposite valve cover.

I never thought either of these issues amounted to a "ton" of work.
