WHLAV,
Another helpful hint! Put something under the throttle body when you remove the screws, so when (not if, but when) you drop one of them it will be caught! A shop towel, piece of aluminum foil, a rag, whatever you have handy will work.
Otherwise it is destined to happen (dropping the screw) just after the hardware store closes, and you are late, or need the car for work, or some other desparate situation. It never fails.
If you manage to get them out without stripping them, put them in with a little anti-sieze compound. This is a good idea for any screw put into aluminum IMHO.
And lastly, when you get the Shop Manual you will find that the torque for these screws is VERY LIGHT. So, don't over do it!
