Default Header install underway - several questions

I've started the install of my TSP headers and CCA tunnel plate. Using directions on the ls1howto website (for FLP headers). I've got the stock stuff all out but I've got some questions before I start putting these in. Here goes:

1. Should I clean the head surface up with some acetone before putting the header on?
2. Should I clean the O2 sensors at all and when I put them on the header should I use antisieze?
3. I'm removing the AIR system; will I need to remove the intake manifold to get the hoses out? Also, the AIR pump is on the drivers side and I use the bottom access panel to get to it right?
4. I'm not using rear O2 sensors. Should I just tape the electrical connection opening up?

I'm sure I'll have more questions but this will do for a start. Before I put thes in I'm going to swap valve springs for some 1.8 ration HS. Looks like it will be much easier to get the air fitting in there without the headers on. Thanks in advance for any advice you can give!

I don't have an answer to all of the questions, but here's what we have done before.

The heads looked pretty clean but we did clean them, they were just dirty nothing really sticking where the gasket was. We reused the stock metal gasket also.

I would try and clean out the header bolt holes and use antisieze on the bolts when installing. The first headers we put on, we didn't clean them out and ended up crossthreading the farthest bolt in the rear.

The air stuff I have no idea.

The connectors we left uncovered(not sure if that was right or not), but it wouldn't hurt to wrap them up.

I think I can answer the rest.

The AIR system routes around the back of the intake. The bolt that holds the line is nearly impossible to get without removing the manifold, so I just disconnected the line at the hose on the drivers side, and cut the line off at the firewall on the pass. side. I will remove it later if I ever need to get in there. The AIR system will need to be turned off by your tuner or you will get a code.

The rear o2's - you can tape it off and your tuner will have to turn them off also to avoid codes.

1. Id clean it to make it seal as good as you can, although the stock gaskets are pretty good i doubt it would matter.
2. I wouldnt touch the sensor itself. And use a very small amount of antiseize so you dont get any running into the sensor itself.
3.?
4. If you dont want to get it retuned to eliminate the code you can get O2 simulators.... or tape them up.
