As others have already said, I like the "new header" enough that I'm willing to live with a little inconvenience. Here are pictures of my work to provide clearance for the header from the #4 cylinder.
I imitated sfdownhill's solution to the problem, I used a heat gun to soften up the plastic so it could be re-formed with an outward bend that gives the #4 cylinder's header about the same amount of clearance as the #2 cylinder's header pipe.
Installed on the bike you can see that I've managed to achieve the same amount of fairing-to-header pipe clearance on both the #4 and #2 headers.
I happened to have some high temperature heat reflecting tape on hand so I added it to the work I did. I figured why not, regardless of whether the situation really needed this amount of protection
Maybe I got a little carried away with the heat reflective taping...
