Had the same issue 14 Ram, 5.7 at 65k. Hooked up w/a friend who was a Parts MGR at a Chrysler dealer. Got new manifolds, gaskets and bolts for $450 n change. Had 2 sheared bolts on the front left side and 1 off the right side. I was able to remove 1 of the 3 but had a friend weld the nut to extract it. Reason for the manifold change as they were warped 1/8" in the front. Going on 11k since, no issues.
