One thing i wonder though in the picture, look how at the bottom of the intake ports looks like carbon build up.

Its like the intake was sitting to low on the head and the air is hitting that lip and backing up right there. If i ever did have any done i would think that edge could be rounded better. Just half moon the bottom edge a little taking that edge off. At the top its more clean which seems like its flowing better.

Maybe this is why they added the "tumble flaps" so the air rolls in at the top where the intake meets the head better?
