I thought this made quite a nice NA hybrid engine? You're forgetting the TVIS system ... up to a certain point, there isn't any problems as the TVIS compensates in the lower RPM range on a stock motor. Once you start playing with it and go with bigger cams, there comes a point when you no longer need TVIS. In Garth's case, there is no TVIS hence there won't be any butterflies to close off the intake, especially in the lower RPM range where it counts most. Just cut n weld the small port manifold Garth - as Witzl said, it's cheaper and there's even a step by step instruction guide on these forums.
