You really need to call Crow, as they will know the lift.
If the lift is too great, the springs will bind and you will either break the spring or the rocker.
If the lift is not enough to bind the spring, no damage will occur, but they may just be to weak and you won't be able to rev it high enough to obtain the full benefit.
No one here can accurately answer your question without knowing the lift of the cam, the installed height of the springs, and the amount of travel which the springs have until they bind.
Call Crow, now.
