Surfactants won't hurt your pre-emerg. In fact even though the label of a pre may not call for the use of a surfactant, it should acually help. Surfactants / spreader stickers etc. reduce surface tension of water. They make water wetter, that will aid in better coverage. Yes they benifit post emergent chems more than pre emerg, but they do not interfere with pre emerg because the dont keep it from being washed into the soil with irrigation.
