your messgae got edited but let me touch on it for a second here...
all airflow tubes/chambers/ect BEFORE injectors (whether it be water, fuel or nitrous) flow better with the smoothest surface possible. in the old days when cars had carburators the fuel was added to the air just after the filter and it that case yes i would agree we wouldnt need to go as smooth since there was an air/fuel mixture and we dont want the fuel to puddle on the sides. when we get cyl heads ported we get tiny spoon shaped divots put into the intake runners to cause a tumbling (in some cases a tiny reverse flow) which keeps the fuel from collecting.
yes it may be a bit overkill for the coating but when we learned that the companies we deal with have the capability to do so we said sure lets go for it. its sprayed and then baked onto the piece at Dart Cyl Heads. They do not have the writeup for this coating on their website yet but its closer to their skirt coating then the others they have listed.
if you found info to the contrary about smooth versus rough please link me as id love to check it out.
