Hole size should be right either way, but this model has shipped from the factory with more than one brand of tuner. Check which ones you actually have before ordering.
Some units of this model have shipped with Wilkinson tuners rather than the Grover Rotomatics Epiphone list in the spec. Both sit in a 10mm hole, so the headstock does not need reaming either way, but the bushing that comes out is not always the same part, which affects how cleanly the replacement seats.
