My advice would be to replace the studs 
you will need to remove the manifold, but you might be lucky and have enough of the stud sticking up from the head to get a pair of vice grips on it once the manifold is removed.
You will probably break a few more while doing so.
worst case scenario you will have to drill them out. use a lot of cutting oil and make sure to keep the drill 90 degrees from the surface. then chase the hole with a tap to clean up the threads.
Plan on getting a whole set and just replace them all. problably need to replace the gasket as well.

If you have access to a welder you can remove the manifold and gasket to allow you room to weld a nut to the end.
This will accomplish several things hopefully to your benefit. The heat will help break the seal and the nut will give you a grip point.
Lots of PB Blaster couldn’t hurt.

I have had next to no luck with this method.
I also would not recommend vise grips.
I like this style stud extractor. I have had very good luck with it, and it does not need a lot of the stud sticking up, less than you need to get a good weld for a nut. I specifically like the Titan brand. Not all of the brands have the same teeth on the jaws. The Titan one aligns with the most common stud threads giving a better grip.
A little heat with a map gas or propane torch will help loosen stubborn rust, the weld on nut trick works well also , or the extracktor, just remember when you go to loosen instead of just pulling on it try to "rock it", tug in small increments, I have found this to work best
