    Pulling plugs you should be able to do all from the top except #8 (Pass rear plug). Since it seems you are pulling the heads, you can wait till after you pull the heads so that nothing fails in. Even if you crack one it's still cheaper to replace then something failing into the motor. If you are still determine to pull the plugs then remove the coil packs off the covers and then you'll have an easier time. Most have to go from the bottom to get #8.

    Also order MLS gaskets don't waste time on graphite. And make sure all head bolt holes are clear of fluids before you install the new hardware. If you have liquid in them you'll not be long in buying a new block.

    Any hickups let us know and we'll help as much as possible. Also masking tap is your friend. Tape over the heads to prevent stuff failing in.

    Another possible bite you in the butt is the OPSU, very fragile and is "conveniently placed on the driver's side of the intake, near the firewall. If not careful when you remove the intake you'' most likely break it because of the brake boost hose that is also attached to the back of the intake. You also have a couple of grounds on the drivers head firewall side and one of the passenger side rear too.

    Make absolutely certain that you get all the fluids out of the head bolt holes prior to reassembly. The hydraulic pressure created by trapped fluid has been known to crack engine blocks.

    I have found that using one of these flexible grabbers and small pieces of towels and keep running them in and out till dry, works best. Also a use compress air to blow out most of it. It's messy but it does work. You can also try a Mitty Vac, but I didn't have much luck using mine.

    Just make sure you account for all the paper towel pieces...
