The gasket really is easy. just label everything that you have to take apart and unplug. I did it in 7 hours taking time and thinking a lot, lookin for a lost bolt and lunch. The only bitch was the fuel injectors I didnt want to take the fuel rail off so I unpluged all the injectors and tried to fish them under the fuel rail that was a PITA. good luck.
