Not spending $500 on the cbm headers lol.
As far as the fuel cell... http://www.ebay.com/itm/251289947366?ss ... 1423.l2649
I don't blame you. I've heard good stuff about the $120 SS ebay header, Ill prob go that route when the time comes, I do hate how the OEM steel header is the only thing on the engine that is a heavy rust monster. As far as the square tank goes, that looks like a nice unit to me, but I cant find room for something that bulky. Have you thought about going with a custom spun aluminum tank? Can tuck those just about anywhere. I've been eyeballing this Co.: http://www.aluminumgastanks.net/options.html
I like how you can have them do whatever you want, prices seem very reasonable for custom tank work also. They have 10", 8", 6" at just about any length. If you don't need a custom tank, there are spun aluminum tanks on eBay that are very inexpensive.
