Over the years, I have installed hundreds of bushings using liquid nitrogen without encountering any issues related to the cast iron being adversely affected.

From my observations, the thin sleeve of the bushing does not have sufficient mass to transfer enough cold into the cast iron casing (block in this case) to cause any damage or structural changes.
