Modding the stock intake manifold (Upper not lower)

After looking at the stock UIM, I really dislike the design. Air go's in and hit a flat wall for the primary runners. And there are hard abrupt corners everywhere in the primary and secondary areas. So i cut it open, sandblasted everything, and ground out most of the bumps, corners, and round edges. I then added JB Weld to help smooth the air flow.

Before i go ahead and weld it back up, anyone have any good ideas to further improve upon this "experiment".

Here's what I came up with:
*These pics are before the sanding, polishing, and finishing.
