Isn't it going to go back to the same color as before?
I see it looks like you have a nice radius feeding #'s 3&4 cyl, did you do the same to feed 1,2,5,& 6 ? Hard to tell from the pics. I had put a large radius on my Cliiford intake & went too far , had to weld up both areas fwd & aft where carb mounts.
It(the radius) helps the air/fuel turn into the fwd & aft runners better & yes & carb spacer does help it does also change the fuel needs a bit also,depending on how thick a spacer you install.
