A general question when increasing valve lift with 1.65 rockers:

How can I know how much lift the valve springs support apart from calculating coil bind? (which will be fine with my combination)
Do I need a certain amount of spring pressure for lets say .594 valve lift?
My pistons have -15cc and block is not zero decked, so I guess the distance valve to piston shouldn't be a problem with less than .600 valve lift.
Heads are d-port Edelbrock with stainless valves that came with it.

Any other things I should check?
