If I were doing them for a living there's a plastic tubing kit where there's a ton of curves and straights that snap together and make each tube (all four at one time). They come in different size tubes and allow for any bend and really look like a header when all snaped together, infinitely adjustable. They start at $245 and go up, no more guessing and trial fitting.
Isn't that the kit that you send in to have the pipes bent to there shape?
it's ok to butt heads, just don't do it with a butthead
