If your rock was truly cured, then you may not see much - if any - of a cycle. That was my case, even with cured rock that was shipped overnight and was only out of water for about 18 hours, but kept damp all during that time.
With cured rock, there might not be much die off at all. If it was me I'd throw some fish food or a shrimp (dead) in there for a few days and watch for the nitrAtes to go up. If they do, and you're not seeing any ammonia or nitrItes, then you're definitely cycled and good to add livestock.
The shrimp may not be "necessary", but it won't hurt anything either.
