They're not that bad. We make a habit of sealing the rubber cover around the valley cover with RTV when they are reinstalled..
basically the intake comes right out, and all the bolt heads stick straight up. We never use locktight on the bolts, but then again, engines don't tend to stay in the cars for 5+ years, either. DO buy a set of replacement intake manifold gaskets before you start, it's cheap insurance. The one to the TB is normally fine though.
Do NOT disable the knock sensors in the tune!
