What kind of restoration are you looking to do? Unless there is damage there really isn't much to do. You're not going to resurrect faint markings with a restoration. That's how you ruin an otherwise good stock.
You're getting new metal bits for the repro stock and not swapping out the ones already installed on your existing stock, right? The buttplate and nose cap are whatever, but I wouldn't recommend removing the recoil lug or the band spring unless you absolutely have to.
FWIW, the kind of light use that a range queen rifle gets isn't going to damage or fade the stamps. Setting aside idiots with sand paper, that comes from heavy handling and the sort of cleaning a gun gets in service (e.g. scraping and re-oiling).
There's nothing wrong with swapping on a repro stock, it's just unnecessary.
