You'll see the cam chain tensioner and guide rails when the valve covers come off. The ends are unsupported, if they're fine, chances are very good the rest of their length is. The timing chain tensioner and guide are in the front of the motor, which you'll want to partially disassemble to inspect the HES wiring anyway. I'd also look at the belt, it may have seen damaged as well.
