These headers are crap IMHO, too big primaries and that stupid 'o-ring' flange. Good headers have thick flat flanges.
But there is no other choice except build your own. I aint got time for that.

Bryon,
Never tighten the CENTER TOP bolt.
Just tighten the 4 inline ones and after 200 miles retorque it.
