The Blue Ice Tele in my sig has a Gibson scale Warhead neck on it with humbuckers, but among other oddities with that body is that the neck pocket was routed for a Strat neck. But, as Rgand noted, you can put Strat necks in Tele heel pockets without issue other than the small corner gaps left over that the overhang covers up anyway and there's no intonation issue. You can also get Warmoth to re-cut Strat headstocks into Warheads for a small up-charge, which I obviously did for that guitar as well. Opens up your choices quite a bit if you want to buy out of the Showcase, as there are a helluva lot more Strat necks than Warheads to choose from. Long story short - the overhang isn't a problem in any case.
