I want to up grade my Edge / Axis rebuild to a full recoil lug. What do I do about the notch in the receiver?

Face the receiver flat and square, as if I was "blueprinting" any other action.
Put on the full lug, nut, headspace and tighten the barrel nut as on any other Savage, ignore the slot/gap.?

Some other way I haven't thought about?

I'm going to pillar and skim bed, with the full size recoil lug, in a Boyd's thumbhole laminate stock.

OK smart pigs, tell me what I don't know...
