Valve spring height

I am running a comp 306 cam with the crane 10308 valvespring kit. Does anyone know what my valvespring install height should be?

1.800" should be fine. These springs have a slightly higher than usual seat pressure of 165, so you don't want to go lower than that installed height to prevent lifter collapse.
