Ss leaf springs on 72 Scamp ...stock length shocks???

So I'm nosing around in the forums search and see conflicting info on the use of stock length shocks because of the ride height change with Ss springs ?? Does anyone know for sure if longer shocks are needed ? Or is it just time to measure eye to eye( shock mounts) while compressed and extended ( leaf spring)? . I feel like this should be a known issue . I'm wanting to go with Vikings and as I say I have Ss springs and cal tracks std. Two hole system . Thanks in advance !
