depends, what are your mods and is that the stock map?
If you have done much in the way of mods then I would say yes, the stock timing may be too agressive up top for your current setup. If not, I don't know cause I never had any logging capability till after I started modding.

Do you have an wideband O2 sensor so you can log your AFR?
Do you have a Walbro fuel pump?
It is possible that w/o a fuel pump and the 272 cams that you do not have enough fuel pressure and maybe running too lean. So the ECU pulls timing to protect the engine from damage. But this is only a theory. You must log your AFR so we can know for certain.

3-6* @ 3400-3800rpm (peak boost)
then rise to 20-24* around redline
also in the rise, there should be no falls in timing.

If you flow more air you will have less timing. With those cams he probably is flowing more air than your used to seeing. Take a tad bit of timing out up top and call it a day. 5-6 counts of knock isn't much and easilly corrected. Even leaning out the stock maps in the upper rpm (withhout touching the timing) area may help cure the knock due to other reasons.
