They're pretty easy except around the booster, the first few sets I did I removed the booster and tied the MC out of the way but anymore I just stack the socket and 2 short extensions into the hole and break it down on the way out. It took me about 2 hrs the first time but it's 30-45min now.

One tip that helps me is I use the numbered plug wire clips and remove the coil packs on 5 & 7, it's less to work around since theyre bulky and space is kinda tight back there.
