That's the correct cam. The lifts are as follows:

Intake: .574"
Exhaust: .595"

The way to determine the lift with different rocker ratios is to divide the provided lift by the size of rockers used to measure it and then multiply it by the rocker ratio you want to use. So in this case it would be as follows:

For the intake: 0.539/1.5=~.359 and then .359*1.6=~0.574

Then you figure it the same for the exhaust. Just need to make sure what they used to measure the lift at the valve so that you use the correct formula. Be careful because sometimes cam manufacturers advertise with 1.6 or even 1.7 rocker ratios but the I have only seen the 1.7 with LS1 cams.
