I would consider my mods depending on the available resources up there... Do you have a good mechanic who is rehearsed in LS-based motors close to you? Headers and a cam are not a big deal and don't require a mechanic nearby, but tuning for nitrous in your area maybe more trouble than it's worth. If you can handle the Shade Tree mechanic skills to install headers and a cam by yourself, I'd just stick to bolt-on mods that can be utilized by a simple re-tune by Allen. Anything else, and you might get over your head without a decent tuner/mechanic readily available...
