Broken manifold studs on my 4.7 PITA!!!!!

How did you make out changing the studs?
Mine were broke on the passengers side my 04 4.7L, the rear 2 bolts. I sprayed them with PB Blaster every day for a week. I have a 3" body lift and 34" tires, so I did not even have to jack it up or take the wheel off or nothing, just stuck my head and arms in there. Everything unbolted with ease and after I took the manifold off, the 2 broken studs unscrewed by hand with no tools. I used a sawzall and cut the down pipe bolts and replaced with grade 8's from home depot. For what I was expecting, work wise, this was a pretty simple and easy job.
