That is what they call a burnt valve. It could have been caused by a few things. Either lean condition, valve not sealing properly, and excessive combustion temps. There are more but I dont feel like getting into all them. It had nothing to do with the timing belt or jumped timing.

Take the head to a good head shop, have them go through it, and while they are doing that check out your fuel system from the pump to the injectors, and be sure it was not an electronic/mechanical issue. If no issues are found, seriously think about your state of tune. That is not a typical problem, and for that to happen.....WOW!
