There's more to it than the finish. In talking to them it seemed like they really focus on getting everything equalized internally (volume, taper) which is what takes the most time. They probably cut more intakes in half than not for that reason. Had I decided to use that hacked up Victor without fixing the runners I would have had some level of cylinder-to-cylinder tuning issues. I very well may have some with the S.V. too though maybe not as pronounced since far less material was removed.
