Get aluminum 8AN fittings, take the valve covers off, drill the holes where you'd like to put them, take them to a guy with a TIG welder, grind off the excess inside the valve cover, paint to taste.

That, all day long. A talented welder will put the valve covers in an oven and heat them up, then do a bead on one, put it back in the oven and do another bead. The job my guy did is superb. Doesn't matter of they're cast or CNC cut aluminum. There's nothing on the inside except a weld bead, which causes zero interference with the rockers.

I did mine that way but did female pipe thread bungs, if I was going to do it again I'd put AN bungs in. I have AN adapters in mine now. I finally did a redo on my breather lines, changing them to nylon braided hose.

It's dusty in there, but you get the idea.20220620_131826
