header wrap? pro's / con's

Wife said silicone spray will be here tomorrow. I looked at the headers today and started pondering how I'm going to tackle this?
Clean and spray with silicone before and after ?
I guess wrap the center two on the passenger side together?
Actually when I look at these things they're all over the place ! 1 tube then 3 tubes together 2 tubes with just enough room between them for one of the two to be wrapped leaving the other one not enough room to stuff wrap without seriously putting some tension splitting them apart and then on the other end if I wrapped it together it will have pressure bringing them together. I'm already thinking about that thing just one piece vertically in between them and wrapping them together on that? It turns from 4 to 3 to going into four and then back into two the back....lol
I'll take some pics tomorrow.
