when I create 2 GUITEXT how can set it up so 1 is only visible in my one camera and the other GUIText in my second camera in the same scene?
oops. found it.
You can place the text in a layer and deselect the layer from the camera
Or better yet you can remove/disable the GUILayer component in the camera.

but than all the GUIText is not visible when do you remove the GUILayer. 
I want some one camera A and some on camera B
