the head might make more power it all depends on the valve sizes bigger valves mean more fuel and air getting in

they will give you more compression ,but the small valve will do you at lot better for low rpm street use ,you will not be able to realize any practacle benifet's with 2.02 intake's on the street 1.70 will be fine .
