Don't port the inlet ports, they are perfect for street use as is.
Don't port the exhaust ports unless you know what you are doing. If you have D-Jet that works, keep it, its manifold will make far more horsepower than the the twin carb B30A manifold ever will.

The big power restrictions in the B30 are the exhaust manifolds & ports. 1st step is to get yourself some custom headers made. 6-3-1 preferably.
