Stock Exhaust Manifold help

I have been double checking all my stock componenets and noticed the following nuts from the Exhaust manifold bolts are missing. I attached a pic of the missing nuts.
My question is will I need some sort of extractor for the bolts that are broke off?
I am assuming I will need to remove the entire manifold to repair those missing nuts?

Any special tips or shortcuts to repairing these?

Thanks for your help!

I saw the other post with the same problem…Searching owns me! LOL

Should I replace all of the bolts and nuts for the head? Motor has 200k on it.
