1971 351C valve cover help

[Fordguy427]

Good evening,

Im hoping for ideas or suggestions, or even some guidance if any one else has run across this issue.
First off, a picture is worth a thousand words….my car has some cheaply chromed valve covers that make me want to puke every time I open the hood.

So once I finished puking I set about to change it. I really like the OEM Boss 351/302 valve covers, but I dont like the price LOL. So I bought a set of Ansen cast aluminum valve covers….so far so good. The issue is that the Ansen’s dont have a provision for the screw on Autolite cap that holds the PCV valve. Next picture is a set of Ford FE valve covers (painted more of a Pontiac blue? Goddamn hack previous owner) that have the proper size hole with the appropriate folded in metal that provides a “ramp” that the Autolite cap twists into and hits a stop after 1/4 turn. So I need to do 2 things to modify the Ansen valve covers….enlarge the hole to accomodate the Autolite cap, modify the hole so it has two notches to fit the Autolite cap, and somehow get a ramp built into the underside of the valve cover to allow the cap to pull itself tight to the cover. Anybody do this before?

Get a grommet and a press in breather cap. You can get the caps with or without a nipple for the breather hose. Check NPD, Kentucky Mustang, or one of the other parts houses for a variety of caps.

The valve covers came with the correct grommets, but I would like it to look OEM correct. Thats why I’m attempting to go with the Autolite 1/4 turn cap with the PCV valve going through the center.
