 The channels are so narrow, that my tig torch barely fits inside.  How about

 heat the entire manifold with a torch, and pool the molten alloy inside the
 runner?  
  
 Thanks for any comments.  I've got to get moving on this intake in the next
 couple days, since I'm burning vacation time to make this happen.

Make a band saw cut into the runner you want to change. Remove the portion
that you want to change. Keep the curf above the area you will want to weld on
to give yourself some margin. Weld up the removed lower portion. Die grind to
aceave the shape it needs to be. Keep trying the lower half of the runner
against the engine until it is the shape you want. Weld the modified portion of the
runner back onto the manifold. Use a needle scaler to make the smoothed out
weld area look stock as cast.

You can do that to a stock class manifold and get it through tech, I am told.
I would never do that myself.
