Ex Manifold Stud Hole Threads Advice

2008 F350 5.4L
I lived the dreaded exhaust manifold replacement nitemare and after a long day I got all the studs and broken studs out.
The very first stud I did was a larger diameter than all the rest. I discoverd that someone did a quick fix and had forced the larger stud about 4 threads deep into the head and left the broken stud inside.
After counting threads on a good stud there are 15 total and the thread count on the broken stud inside was 11.
Do I need a helicoil kit or can I make do with the 11. In the attached pic you can see the threads...there is a piece of the easy out that broke when I tried to take the stud piece off it.



All advice and experience is welcome. Thanks

11 threads should be enough. The photo of the studs shows to me that you would have plenty of the stud screwed into the head.
