very hard to tune a short intake with one hell-of-a reversion when the intake closes, flow pretty much stops for a milli-second or so. sticks burn better than logs so a little roughness helps break things up.
now if you have to remove material from either side to get a very good alignment, go for it. however, most really do not care and the ole iron putts on merrily for over 1/2 century.
