I've done it for about 4 months while I was taking this one class that was about an hour drive away. So 4 days per week, 2 hour trip there and back. It didn't foul my o2's and sounded awesome (at WOT it was insane). I personally didn't mind the loudness (you get used to it after a while). So... my personal experience was good.

Just get a 3 inch to 2 inch reducer and 90 deg turn out to put on till you get there. It will keep some pressure in the tube and keep the raw air off the O2's. This way the PCM wont be dumping more fule to fix what it thinks is a lean condition. Thats what kills the O2's is how rich it is going to be running.

Pretty sure the valves aren't affected unless you run it with no headers (straight out of the exhaust ports), if you've heard about header/manifold leaks hurting valves, it's from the port end where it hurts.

there slip fit right? I think they are and I think they use a 3 inch out side diamiter collector. So you need a 3inch inside diameter reducer that will slip fit over the collector and then reduce down to 2 inches. I bought parts and made one years ago for Vette projects I did. I have just kept it for that reason all these years. It comes in handy. I would put longtubes on my vettes and then drive them to the exhaust shop with this reducer on there and never had any problems. They sold them for a shot time a couple of years back at advanced and auto zone but the selection in any store sucks now. 30 miles on open headers is a way with out doing something like this or having it towed there.

It wont hurt the valves but the damn thing may barly run by the time you run 30 miles on it like that. The O2's are going to be toasted. I had the fuse blow on my O2's last week and the damn thing just died everytime I got off the gas. You can chance it but Plan on new O2's

No, valves won't be hurt.
Heat's the real concern though. Make sure nothing is in the way of the hot exhaust; nothing that can burn like wires, cables, etc. Also, minimize idle time.
I've done what you're planning to do MANY times over the years.
