Hi Clois, if you switched from an open plenum to a dual plane, that can make it drivable at low rpm and off idle, reduces the amount of reversion from one cylinder to the other with the higher overlap, etc. It is possible changing to a smaller cam with the dual plane you increase low end hp and could end up with not what you are looking for.
