I slept on it and decided on a careful approach to clearing the jam. One by one I removed each heatsink and placed a piece of a silicone mat blocking airflow to the heatbreak allowing it to heatsoak to the 240c temp of the nozzle..

Upon teardown I realized there is no thermal paste on them threads on the cold end side. This is important. And I just happen to have the best thermal paste money can buy. Thermal Grizzly kryonaut. So a little of this needs to go on the threads of each heatbreak only on the cold end side..
