I installed the bolts as recommanded in this vid http://www.youtube.com/watch?v=Ibq8MFtjBj8&t=25m40s. If I flip the bolt arround it's not possible to push the long bolt with an angle in that hole.

I didn't tighten only one side of the flange. The flange is hand tightened on that picture to show you the gap. I know that you have to tighten the bolts in cross to avoid leaks.

Why are the flanges staggered if the flanges of the exhaust aren't?
