Get some Pro Circuits or PT Mids for pipes, pick up some vf2 or 3 reeds, 28mm carbs just to name a little. Call a builder from here and talk to them about porting to your riding style and what combo of reeds, pipes and carbs to go with. It really depends on how much you want to spend and how quickly you plan on doing it.
I personally run PT mids, vf2, and a 2-1 trinity intake with PWK35. It's perfect for the riding in do in my area. It's defenately a broader powerband down low. Porting is my next set for just a bit more.
