1.6 Roller rockers

I have a 1989 camaro Rs with the 305 TBI engine, and my question is this, i would like o put 1.6 Roller rocker arm on to open the valves a little more, do i need to put longer or shorter push rods in to correct for the 1.6 ratio or can i just put the rockers on??

Just make sure that the pushrods don't run the slot in the head after changing the rockers. Sometimes the pushrods go a little farther out and rub.
