I just finished removing the powder coating and contouring my stock upper intake. Yea, I'm bored and having nothing to do in case you were wondering. I took out all the ribs, seams, and dimples in the intake. It is all one smooth piece now. Tomorrow I'm gonna start with 80 grit to smooth out the spots I ground. Then start with 200 grit on the rest of the intake. After that let the boredom begin!!! I don't have a camera, sorry 
or else you'll be doing a lot of sanding. If you ever get a camera, get some pictures.
I love the look of a polished edelbrock. Wish I had one myself.
