On the good side the bumps appears to be the worst of the battle damage. A post race compression test was performed. The results were promising:

These results do, mean that both engines are good enough and can be used for the next challenge. Of note we did find some troubling signs of early detention on the Z. When the spark plugs (from cylinder 1, 2, and 3) were pulled they showed electrode and insulator tip damage. The guess is this happened during first day's practice. This is something that we keep an eye on going forward.

As for other parts, we seem to get out with little other issues. Here is the list of work that showed up:
So, all in all not that bad.
