On my teener dressed as a 273, when I installed the crane adjusters, one hit the baffle in the valve cover. Had to massage the sheet metal some to keep from hitting. Commando Valve covers.
I kind of expected I may have to do the same as you.
I have a set of covers that are wrinkle black with chrome cooling fins that have a notch for the plug wires to sit in, have no idea what they are but the look pretty cool and have the wire looms built on.
