A little update - found a thread on the FB Ventana owners group and apparently its not all that uncommon to have the exhaust manifold on a 6.7 warp between 60k and 80k miles. Mine happened at 67k and I still think it was precipitated by the low boost condition, but this is a “known problem” for which Cummins takes no responsibility, naturally.
