Not familiar with the Z's need some help spending money!

Z1 headers/test pipes or cats, cat-back, tune, done. I'd do a CAI as well, but that's a debated topic here. Do your reading and make your own decision. The Motordyne intake manifold also has some nice gains. Get the tune after you get all the parts on so you only have to do it once. Plenty of people have had good luck with pulleys, but they make me nervous. That's about it for NA mods. You'll end up around 330 whp dynojet, give or take 10%.
