Which of these would you do first:

Headers
Ignition System
Roller Rockers

 

First of all...what mods do u have now?

If u already have a catback/intake...then out of your list of 3, i'd do headers then probably RR's..

I would personally take the ignition off your list. You dont need it. Not now at least...

 

Headers are a great mod. Aside from the torque converter I have, they gave me the biggest gain

 

get the headers, easier than the Roller Rockers and a better mod than the Ignition System. at this point in time for you.
