All of them, as far as I can remember. Its a required emissions component.

Possibly, but it depends. When I bought my longtubes for my LS1, they had both emissions and non-emissions versions. I bought the emissions version, with AIR provision (but no EGR since 01-up cars don't have it).

Well the thing is I just got this car and Im in Iraq and havent been able to see the car physically. I found a good price for some headers but they w/ A.I.R. only. Dont know if my car has it or not.

Basically dont know if I should get these headers. The price is awesome. Anyway to tell if it has it or not? Its not a CA car, Im 100% on that.
I live in Ohio and a friend has an 87 IROC w/ 5.7 bought from a local dealer, it has the tubes on the stock manifolds. If they are cheap in price... why not just buy them, if they don't work out for you then ebay em' or sell them in your hometown newspaper etc.

Weird. My 85 Berli has no indication of ever having an air system. No tubes, no wiring, no pump bracket.

Clean removal job by a previous owner maybe? I don't have any experience with 6 cylinders, but I don't see why it would be any different.
