5.7 hemi manifold bolts?

Ok so I am getting a leak on my exhaust. You know the one the fords have because the owner is to cheap to fix will the correct part.

My dealer is telling me that the bolts for these manifolds are cheep stock and because the heads are aluminum and the manifold is cast that all the hemi's are failing. The bolts just randomly snap off. WTF is this cat full of chit. I have not pulled the truck up on the hoist yet to look.

Thoughts?

Don.

That's the way it is. I see it on fords, chevrolet, dodge, toyota, and nissan.
