Biggest pita is removing the upper plenum. Loosen all the plenum bolts and take out as many as you can. Some of the bolts in the center are not removable. The ones that aren't removabe have to be held up as you pull the plenum off. You need to unbolt the fuel rail and lift the rail and injectors as one unit then leave it laying on top of the plenum. After that's off it's all cake.
Make sure you replace all the head bolts with new ones.
