one shitty thing about the job aside from removing all the parts is fucking around with the spark plug hole gaskets. one thing that bugged me a lot was the spark plug hole gaskets which after much frustration, figured out that you need to get a vice grip, grab a really good chunk, then pry it out by pushing down on one end of the vice grip like in a see-saw motion, careful to put a towel under the vice grip so you don't mar anything. Heating up the valve cover in the oven or with blow dryer so it's warm also helps a lot when re-installing those spark plug hole gaskets. It's also important to lubricate them as it's a really tight fit, then push them with a large flat surface like the back side of a 30-34mm (can't remember) socket and hammer just a little (careful not to damage them). If you don't do it right you'll have to remove the gasket and start all over with a new gasket.
It's easily a 2+ day job for an amateur to do. The ETCG video is excellent though he doesn't cover the replacement of any gaskets. Might want to shop around for a price quote on this job and if this is your only vehicle, that you have no backup vehicle, you may not feel comfortable enough to do all the work and have it done in a timely manner.
