try this, first determine what the actual lift is on the cam its self .563 / 1.5 =.375333333 then multiply that by the new rocker ratio which is 1.6 that will give you .60053333 i believe that would be correct. Someone tell me if im wrong.

So if I do the same with the .545 in. I would come up with the lift. And it would be .581 if im right.
