Thanks for the detailed info. I had realized a while after I posted that there was no way to clear the fuel rail with the lower intake. I better gather the parts before I pull the lower intake so I don't have to leave it apart too long. In the meantime I've cleaned up the upper and lower portions of the plenum and the throttle body, making sure to keep the cleaner out of the sensor, as I could not get the screws out. I also realized this is probably going to take me some time, so I had to temporarily put it back together and get the cooling system flush out of the system. This is what happens when I try to do two projects at once. :-P
In other good news, now I understand what the isolator bolts are/look like.
