Ford Repair: exhaust manifold, minute intervals, penetrating oil

Question
My 1997 expedition has a warped left side exhuast manifold. what can I do to ensure I don't snap the studs off while removing the old manifold. I have all new studs for the new manifold?  The motor is the 5.4L. Thank you.

Answer
Buy about 3 cans of the best penetrating oil that you can find. Spray it on the studs in 15 minute intervals. Let it sit over night, and repeat the process. This should ensure that the penetrating oil does it's job. Exhaust bolts have a tendency to break, so just take you're time.
