adjustible rockers

i just got a set of comp roller rockers for my car i have done some research on them and cant find any straight answer. do you guys think i am going to nee to shim the rockers from one another or should they just line up correctly

Fittng roller rockers is never a out of the box deal. You need to make sure the roller tip is centered over the valve tip as much as posible which will take some shiming usually.
