Race Headers on a street car.

That is what i was thinking. I figure 2" would be required. I know i'm gonna need a custom cam, just not sure if it will be flat tappet or roller yet. Still studying and learning...I have always wanted a big small block and have a 340 or 360 block to choose from. I figure the heads and intake will be my limit, but I have the W2 heads and all the related parts. They are ported but i want to redo them to the cam i end up with. I have thought about trick flow heads also.
