I believe the instructions that came with my threadless headset said the steerer should be recessed about 3 mm below the stem. That compares to your 1/8-1/4". Remember you tighten the headset by turning the cap bolt, thus applying pressure to the stem. If the steerer extends above the stem, there is nothing for the cap to press against; you can tighten the bolt until the cows come home or the star flanged nut pulls out and it will have no effect on the headset. So yes, stick another spacer of appropriate thickness to get about 3 mm. I can't recall if this is a new bike, fork, etc., but if you got it from your LBS take it back and let them do this.
If it ain't broke, mess with it anyway!
