lift with rockers

My cam's lift is .489, so what would it be with 1.6 rockers? I multiplied .489 by 1.1 and got .5379. Would this be right?

No, that is not correct.

Divide the 1.5 spec by 1.5, and multiply the result by 1.6. That gives .5216".

No. Divide by 1.5 to get lift at the cam lobe, then multiply by 1.6 to get actual lift. So .5216
