"How do your timing chain guides look?"

Educate me. How should they look?
and
How did you check for play in the bearing bracket?

Keep in mind, I left all of that on the front of the motor. There is no play in the fan at all side to side, though I can slightly move it forward and backward. There is no wear on the cam sprocket and the chain just barely lifts off of one tooth when I try to pull it away from the sprocket.

Still need valve to guide clearances. Anyone?
