The best bet is to ignore both stock intakes and build your own short runner intake. This is not always possible. 
Next best choice is a TII intake if you can do a good job port matching. The TII intake doesn't use any of the tricks the NA intakes do and is a simple plenum/runner design.
After that, the S4 intake. Gut the dynamic chamber so it become an empty plenum.
Finally, the S5 manifold. Never a good choice on a heavily ported engine.
