I don't understand why valve guide material would dictate the type of rocker arm you need?

Also, smoking is usually bad intake valve stem seals and or a broken ring or bad head gasket.

The LS rockers side load the valves because of the "scuff pad" tip. A roller tip is supposed to alleviate that so you can use bronze guides, which would otherwise wear quickly because of the side loading problem. That's the theory at least. Not everyone agrees that it's really that big of a problem.

That's why I bought the heads use in the owner before me use stock rockers n when we put the car on the dyno in rev it. It started smoking like crazy

Usually the guides will cause the engine to smoke at idle and maybe part throttle. That's when there is a vacuum in the intake and it pulls the oil into the ports through the guides. If it's doing it when you're giving it some RPM, it might be something else.
