Doesn't it have Outrage and Grass Knot?
... fair enough. So I thought of another EV distribution.
Since I don't have mints, changing EVs to 76 HP / 240 Atk / 192 SpD, and equipped with a Float Stone, Golurk avoids the 2HKO from a minimum Special Attack Grass Knot (assuming it doesn't have Special Attack EVs), and even a max Attack Outrage (I guess it doesn't have max Attack, but...).
