changing rocker ratio puts more strain on the rockers and the valvetrain in general. You are giving the cam more duration and more lift, something you should have done when you swapped out the cam in the first place.
Stick with 1.7s. In fact, stick with stock rockers unless your heads require you to change them. Some aftermarket heads have a change in valve angle, which requires a roller rocker.
