Ive seen this happen with .550" springs and all way to .675"+ springs.
The problem isnt the spring pressure, its the weak area of aluminum that the hardened seat for pushrod sits in. That area normally is "beefed up" to withstand the pressures applied to it, but in the Ls case rockers, these aftermarket aluminum ones run a thinner area there to allow clearance of stock valve covers and such. Any taller and the pushrod side of the rocker will hit inside of valve cover and scuff against the gasket rail of the head.
