Just remember it all needs to work together. Heads and cam make a huge difference, but you have to match it with the correct intake and carb. People go put in a big lopey cam, it sounds cool, but runs like crap, because the power bands don't match other components. If its a DD type, then you don't want the car idling at 3,000. You can spend a pile of money and be disappointed. Research pays off big time. I would suggest that you go to mfg websites, such as edelbrock, comp cams, Holley, crane,etc. they have great Dyno info. You can put together some good combos.
