I've been meaning to post pics and do a write-up, just been too busy. You mentioned the intake, don't know if you're talking about the intake manifold, but even the harder write-ups I read through did not have you removing the intake manifold.

I was only referring to the airbox and intake tube. It's in the way. I'd love to know how you got the valve covers off without removing the coilpacks...they are directly over the bolts. While I believe you that this IS possible, I don't think this is a good way to do things. It's often much less time consuming to remove parts that are in the way than to work around them. Considering the coil packs take about a minute per bank to remove...and disconecting the injectors, (leaving them attached to the rail), is equally quick.
In addition, I would recommend making sure the gasket surfaces are 100% perfect before re-install. On mine, I bead blasted both covers, and repainted. But at the very least, I would want to make sure any remnants of sealant or pieces of old gasket are gone. This is MUCH easier to do while the cover is upside down on your workbench; as opposed to still attached to the ignition. This is not a job I want to repeat anytime soon. Again...mine is an M62, so that's what my experience is based on.
