I do not think they recommend chaing them.
Timing chain and gears do not wear much on the GM V6 or V8 engines.
To check for wear or slack rotate the engine back and forward by hand and you can feel slack.
Or to check for true valve /chaing timing the No 4 cyl valves will be rocking when no 1 cyl is on TDC comperssion stroke.
Let us know how much slack you have.
