I'm gonna pass on doing this for people... I really don't have the right tools to make this mod enjoyable, plus I killed my Dremmel doing this anyway
edit: I bought the manifold pretty much as you see it, the inside is ported a little as well. I did polish up a few missed exterior sections with my 18v Ryobi random sander (and it's not perfect by no means!) I also purchased an extra set of TGV's that already had the motors and rods removed and the dividers were cut out. I simply had to plug the holes and smooth out the ports, and paint!
