If it's carbon it's because it's running rich

All the carbon in the world won't make it ping.
Stated in this thread more than needed what it will be.

If you can't make it better why waste your time. No use repeating the orignal mistakes. I'm to old to push it that's why.

I adjusted the timing to 10 BTDC as per oem specifications and took her on a freeway run again. I only got it to ping once right when I got off the freeway, maybe a small improvement? I've been trying to get it to ping stationary in gear so I can take a better video but no luck so far.

This indicates to me that you have other problems. You won't get it to ping standing still. It needs to be under load aka moving. I'd check the egr operation. Whats the temperature after a ride on the highway? Also if you have a vacuum pump you should check your vacuum advance. Read this

Do a search for ping on this site and you'll see all the causes and then address each one.

Not entirely true.
If you have bad gas it will ping in gear standing still(foot on brake) putting a load on engine(reving engine).

At correct idle speed with vac hose plugged? If so it's way advanced.

You didn't say as much but you imply that this is a sudden on-set. In which case maybe your vacuum line to the EGR came off or is cracked & leaking. Pinging caused by other reasons such as timing or carbon build-up don't just start all off a sudden.

And if you can diminish or eliminate the pinging by backing off on timing, all the more reason to suspect EGR not working. Thing is, backing off on timing will now lower performance.

Were you able to get the pinging/knocking issue resolved?

Low oil

You probably checked this, but if your oil level was really low, a sharp turn could send the oil to one side of the pan letting the oil pickup draw a bit of air (instant valve clatter) and then be re-submerged when the oil settles in the pan after the turn / acceleration. This could happen fast enough to barely affect the pressure indicator. Seen this before on a really leaky engine.
