BRR is right, if you go the UEL header route, all your other mods will be fairly pointless from an overall improvement point-of-view, the stock EL header is not bad to start with.
I would (and did) go with a 91 octane tune also, with all the mods I have I would say the mpg is at least as good as the stock car, maybe better.

cams cost to much better off doing a swap
- Yes to EL headers, HFC, 2.25" piping, 91 octane tune.
- The jury is still out on intakes for the 08+ cars, a lot of people have reverted back to stock, myself included. Driveability suffers for the few HP you gain at redline. (Note that I haven't yet tried a tune to account specifically for the intake yet).
- A LW pulley is one of the easiest, cheapest and (probably) safest engine mods you can do. Yes, HP gains are probably unmeasurable but the engine revs a little easier, and (for those with a 4EAT) engine breaking is greatly improved.
- Cams are dirt cheap, a set of Delta 1000s cost around $250, it only gets expensive if you have to pay for the install labour.
