Awesome! I somehow missed the link to the pics earlier. One question about that foam tape: Isn't open-cell foam... permeable? But it wouldn't make sense for weather-stripping to be permeable, would it?
I had a quick fiddle with the boots already. I'd say they're currently about halfway between your new and old ones. Install/uninstall is plenty easy. I'll take a closer look when I clean it all up. I hope to keep them, as I'll be spending enough on the front boots and o-rings already.
Yeah - this'll get expensive quick if you're already replacing the carb (aka intake) boots - bummer. Good move though, and make sure you get viton o-rings that'll take the heat. Robert Barr sells them cheap with a stainless hex bolt kit that'll save some time next time you need those boots off. Well, if yours are still moderately flexible you may get away with it, so give it a shot. I might get flamed for saying this, but a little silicone in the grooves when you reassemble them to the airbox might buy you some time on the old boots.
Check for an alignment mark on the boots and airbox. Not sure about the '80, but my '81 had left and right hand boots, and if they're in upside down you will think you've lost your mind when you try to fit up to the carbs. Ask me how I know. :-D Anyway, the fiche will tell you if you have right and left handed boots. Handed boots?
Meanwhile, yes, it's open cell but it's not actually permeable. I think in this case (with the rubber foam tape) the open cell refers to the fact that the edges show the bubbles. It's nothing like, say, polyurethane flex foam that's also used for weather stripping. That stuff's more like upholsterer's seat foam.
