Just a bit of clarification -- steer tubes are butted, but at the bottom (crown) end, not the top. If you need to trim a long steer tube and cut new threads, there is no need to extend the threading any further than absolutely necessary -- about 2cm down from the top of the tube is plenty. Aftermarket forks are threaded well down the steer tube to allow for trimming without rethreading for a wide range of frame sizes; you don't need to do this if you know how long the steer tube needs to be to fit your particular frame. Although the threading will remove material from the steer tube, your stem will certainly extend well below this point.
