Interested in how boring out the valves will work out.
You don't need a new crank, I'm sure yours is fine and any machine shop would agree. You don't need the fuel rail either. So there's ~$600 you don't need to spend. Stick with the oem manifold until you start making big #'s and it actually proves to be a restriction of air flow, in which case, for 450whp, porting the stocker would do just fine.
