Ok, trying to decide on 1.85 rockers on a cam with a .570 lift. I come up with a converted lift of .602 lift roughly. Does this look right. I used 1.75 as the stock rocker ratio. Also is there a formula to determine how much the duration will change?

If I remember correctly, the stockers vary between 1.70 - 1.71. You're looking at roughly .620 lift.

that's what I was afraid of

Yup. A lot of lift. I've had some of the same troubles. We were expecting my Jesels to be 1.90 and they are 1.95. Ugh.
