As Bob stated they are zero lash. Since they are non adjustable rockers you just torque them down. Unless you've had machining done such as valves or head surface ground then there should be no problems. If you have had those done, then you meed to check lifter collapse and use shims(sold by various cam companies) under the rocker pivots to set the collapsed clearance.With early cast iron rockers it is.075-.175 and with later stamped rockers it's .100-.150, I always go for the higher end to get as much rpm as possible.
