Manifold Nuts...Help!

[Ida4runner]

Leaky manifolds on my 4.7 is forcing me to replace them.
Question:
Any tips or advice on how to get these nuts off without shearing the studs?
Does anything like penetrating oil,heating nuts, moving the steering shaft, body mounts or tire make loosening or getting access easier?
Thanks for any advice!

Hi Ida4runner,

I could be 'completely' off base on this one but the heads are 'Aluminum' so rust wouldn't be an issue; except through the manifold itself. With the engine cold I'd saturate the ship out of those manifold bolts... a few times (every half'n hour, three times: "Don't drive it after spraying"), and they should spin right out!

rig, cheers!
