These are the heads off my WRX. The exhaust valve clearances were below spec likely leading to the burnt valve (missing chunk) on the #4 cylinder. You can also see the bent intake valves on the same cylinder that I managed to do trying to get the cam sprockets off.
My Mozy cost is about to go through the roof, so I'm jumping ship for Backblaze. Not as feature rich yet, but they're committed to cheap unlimited backup (check out their custom "pod" design). Works for me!
