Well I started tearing down the 911sc engine this afternoon. I removed the CIS, Fan, Exhaust, etc. The Damage to the engine started to become apparent after removing the CIS. All of the damage seems to be on #5, but I will know for sure after I pull the heads off.
Has anyone seen damage like this before? The consensus seems to be that the engine was over revved however the PO's son (who was driving the car at the time the engine blew) swears that he was around 4K when it blew.
I have a couple of the pictures posted below, to see the rest check out:

Same as above, but better light and angle:
Upper valve cover off (uh oh!):
