A few thoughts since I've been through hell and back with my car and AN fittings!

1. Can you route the fitting closest to the starter on the bottom side of the other fitting? That could be accomplished with your current fittings or an adapter fitting and different hose end.
2. Use an adapter fitting with a tigther radius. Male-Male adapter and straight hose end.
3. Will the headers be ceramic coated? I've got one about that close. I had no choice. I used heat sleeving and I sleep good at night. That being said, I'd look for an alternative first. Of course using all radius fittings.
