There are any number of threads here of folks asking whether something atypical will work...like shimming spigots to account for case warpage. I think you are luckier than most in that you've gotten several answers, mostly which you were looking to avoid.

Fact is, you've saved about $1k by not having the "normal" mag case machine work done: case halves resurfaced and align bored then the spigots decked. Nobody can really answer when you ask what you can expect from going your own route. The successful builders simply don't work this way. Now, it's simply a gamble on your part to continue. Please keep us posted on whether you set the example or you end up being one.
