If you got powdered metal guides you can use stock rockers, if you didn't then you need to upgrade your rockers.

Just make sure you break or grind off the little tabs on the bottom of the stock rocker pedestals before you install them if you don't then the base wont sit flat on the mounting surface and can/will cause issues in the future

This.

Basically TEA offers them or you can buy heads through their vendors. If yours don't have them I'm guessing you'll have to send them to TEA unless there's a machine shop near you that can do the work.
