Exhaust side of head stripped

Exhaust side of head stripped
Hello,
I have a 1.6l miata engine that's getting prepared for turbo and bought some better Exhaust studs. So I was cleaning the threads on the Exhaust side of the head with a thread chaser and on the very last stud hole my thread chaser somehow fouled up and got stuck, I had to back it out with force and with it the threads were gone.
I've found this post: https://www.miataturbo.net/engine-pe...threads-81900/
and it's a fixable mistake...
My question: I noticed on 1.6l heads there are two unused exhaust stud holes (pic 1)
I messed up the threads on the upper left part of the head (pic 2)
Is it possible to set up the stud configuration like such (pic 3)
to provide adequate clamping of the manifold to the head?
Or do I need to repair that hole and go with how the studs were originally setup?
My reasoning is , to me the configuration in (pic 3) seems symmetrical and can provide a proper seal if I tighten the nuts evenly around. I also saw this miata head (pic 4) with a similar configuration .
Thank you for your help,
Drew
