youll want to put your stock rockers back on with a cam.
a great cam is the XP cam. easy to daily drive and will get you good amount of power along with a pulley swap. you can probably run a 3.2 to 3.3 depending on what car you have. i would say go with a 3.3 and run a higher amount of timing, that will compliment the XP cam. youll want at least #90 springs too.
