Clearly the ozone being ingested into the engine is the root-cause for the observed cylinder head corrosion.
Who woulda thunk?

Porsche engineers think of everything. They knew that those intake ports above the radiator, attached to that cylindrical plastic tunnel, would lead mice up to that wonderfully delicious air filter, and provide the perfect home to store nuts and hide out. Since most 928 owners of the period didn't even know what an air filter was, much less think to check it or change it, Porsche knew that this condition and the associated damage could go unchecked for a considerable period of time. The obvious solution was to capture and kill the mice while they were in a panic-stricken and hasty exit from the airbox after the engine starts. By the time the mice get near the opening they are exhausted and disoriented from the engine noise and fighting the significant headwind of intake airflow. A perfect place to have a trap door for the mice, through which they fall directly into the rapidly rotating machinery in a wood-chipper style execution.

If yes then why where the holes not deleted on the 32V 928 engines which use the same rotor?
