Well as an additional margin of safety, it would be prudent to monitor for knock.
I do my own calibrations but concurrently monitor AFR and Knock.

The LT-5 is not prone to knock at the top end. If u keep advancing timing say in the 6-7500rpm range, you will find that it simply loses power. However, there is a point between 4000-5500rpm where u will see knock if timing is too advanced. Also, it helps in terms of adjusting the AE (acceleration enrichment) which may also cause knock if insufficient.

So as a rule of thumb, good idea to datalog not only AFR, but also the ALDL
stream if u can.
