How close to the soffit vents under the eaves can I place my exterior wall rigid foam?

I’m doing a curtain wall retrofit, so even though my polyiso is only 4″ thick, I’m actually extended a good 8″ away from the original wall.

Anthony,
I don't understand your question.
First of all, if you are installing 4 inches of polyiso, why is your new assembly 8 inches thick? Are you installing brick veneer?
Second, as long as your new wall doesn't block your soffit vents, and as long as you have enough of a roof overhang to keep most of the rain off your wall, you shouldn't have any problems. But I'm guessing there is more to your question than I understand. Maybe you can post a photo.
