mopar or edelbrock intake?

what i want is to get as much horse power out of this engine without boring it and things like that.I figured i would change the cam ,intake,carb ,and headers.but being new to all this ,i would like to knoww what setup would give me this.(i hear its best to match these things).I dont know what cam,or even the difference the lifts do.just a good healthy motor. maybe around 300 hp?
