What about specifically with the upper intake manifold from Stillen will the Z1 ported lower help? It's the setup I'm looking into running.

The ported lower will yield more horsepower depending on the porting that is done, we are currently working with our ported lower and will be providing dyno graphs of before and after to show the gains with having the lower ported.
