The stock rockers in these motors are 1.6:1 ratio, so they multiply the cam lobe lift by that ratio. 1.7 ratio rockers will provide more lift than stock, and that lets more air into and out of the motor, which makes more power.
Installation involves removing the upper intake and valve covers, and then replacing the rockers. You will also have to remove the baffles inside the stock covers.
