I see by the pictures you used a board to gain the clearance you needed for the long tap knobs, I was going to tell you that MM has chrome or gold extentions that when added to the flange ring would do the same thing. The picture was a little dark but I could see it. I have done the same thing for customers a couple of times, the best cooling comes from a pass throught system if you can use it in the location.
