    cam is your best bet to making power but take note that "big cams" that have lots of duration need more compression to work properly(and revs). combining a cam and high ratio rockers works well, however with stock heads you limited to about .520" max valve lift before you have issues so you will need to make sure that any combination of cam/rockers doesn't exceed max lift, or rebuild the heads to suit more lift
