Yes, you are correct. Just be careful and don't bend it anymore than necessary. I would recommend that you get a set of very thin open-ended wrenches to get the EGR tubes off of the EGR valve.

I just got done doing this exact same job (just started it up last night at midnight and it isn't running right....but that's another story). Getting the EGR out is a major PITA, but you pretty much have to take it out because the lower plenum has a very long "tail" that hangs down about 3-4 inches. This tail is what the two EGR mounting bolts go into.

A word of warning, when I did mine, as I pulled the lower plenum up, I forced the EGR towards the firewall to get the plenum out. Bad mistake. When I went to put it back, the EGR feeder tube seemed very loose and could move about an inch an in direction (NOT good!!!). Turns out there is a feeder tube from the left exhaust manifold to the EGR valve (22mm and 24mm, respectively) that I cracked at the point of entry to the exhaust manifold. I decided to take it out and replace it - very good decision since it had a hairline fracture on the flange inside of the nut.

This is very hard to remove, but the easiest way is to remove the brake master cylinder (if you haven't already) and loosen the exhaust manifold end of the tube. I ended up using a flare nut crows foot with a flexible head ratchet to get it on and off.

If you need any more advice, let me know.
