Changing rockers from 1.52 to 1.6s shouldn't have any effect pushrod length.
Valve lift, however, will increase in the range of .030" which means that your springs have to have able to handle the higher lift.
Also, if you're moving from Self-Aligning rockers to NON Self Aligning rockers, you will need to buy guide plates and hardened pushrods.
If you're going the other way round, from NON Self Aligning to Self Aligning (not recommended) you'll need to remove the guide plates.
You should never use SELF ALIGNING rockers and guide plates at the same time.
Hope this Helps.

Normally the effects of changing rockers is so minuscule there is no reason to change pushrod length, however just to be sure your rockers have a good sweep you can at least take a few minutes to check and see...
