Stock Exhaust Question

In reinstalling my front header pipes, I've realized that the flanges are not symmetrical . Looking from the top down, which way is correct, A or B? They seem to fit both ways. Can't find the answer in the manual.

I honestly don't think it matters, but someone else with more knowledge will chime in if I'm incorrect...

Well, if the studs are equally-spaced, 'B' gives you a bit more exposed surface area to the windstream for cooling. I don't run a stock exhaust. Are there any clearance issues w/the frame, the crossbrace, the stock horn, or anything-else? That would tell you.
