Big block oiling mods

Moparmaga ,
Did you put the restrictions in the block or the head ?
I was wondering about putting restrictions in the head,,,,actually up in the pedestal,,,on top ?
That way if I needed to swap them out for something bigger,,,,I would only have to pull the rockers ?
Wouldn’t need loctite or anything,,,,the restrictions couldn’t come out,,,,the rocker shafts would hold them .
I don’t know,,,,maybe that’s where people put them already,,,lol .

Drilled and tapped into the heads, used carburetor air bleeds, in the pedestal, with a little red loctite, I think the rocker studs I have would definitely hold them from going anywhere else besides where they are.
Great thinking!!!
