Re: Replacing intake gasket...

The Felpro set comes with nearly every gasket and O-ring you need to do the job. We did have to go to the dealer on a quick run to get an O-ring for the press fitted heater tube, but that was only a buck.

We also used an RTV sealant that is used in the shop. Apparently is is much better than the stuff recommended.
I used the Felpro PermaDry Plus Gasket set. Unfortunately, the Upper Plenium Gasket was cardboard like material, which if not carefully could easily break. I installed it in my 2000 Malibu on 12/06 at approx 148K miles and still holding at 173K as of 6/27/08. Definitiely used RTV, reused the intake bolts that came on the car. When I removed the spark plug wires, I only removed from the row that was towards the radiator, the spark plug wires towards the firewall, I left them connected to the spark plugs. Instead I only unplugged the electrical connectors on the side of the ignition coil module pack, then remove the bolts holding the ignition coil module pack and just set it aside.

While I was at...
Replace the thermostat, because of age and easier to get to, since the manifold was removed

Replace the o-ring that drives the oil pump shaft, usually known to go back and a common place for oil leaks.

Tips I learned from other people.

The stud that holds the ignition coil to the rear valve cover can be removed, which helps remove the rear valve cover, I did not do this however.

Someone was able to remove the fuel injector rail from the intake without disconnecting the line. I believe that you would only need to remove the nut that holds the fuel line clips to the rear of the engine
