I have used "NOS Octane Booster" in my 1966 110 Monza for years now, with good results.  I use "premium" gas which is as high as you can go here in New York, of course it's garbage compared to "Premium" back in 1966.  The engine runs and idles more smoothly with the NOS.  Unfortunately retailers like Walmart no longer carry this stuff, it may be considered hazardous or for off-road only, etc.  But I was able to find it on eBay.
Before I found the NOS additive, my engine did ping when it got hot.  In addition, I made several other mods to my engine to keep it running cooler, including flashing the heads, ducting the air intake to the cooling slots behind the rear window through the firewall, adding puller fans to the condenser, and finally, a water mist system that sprays a fine water mist into the fan area if oil temps go above around 260 degrees.  You could do something similar with a water injection system.
Even with my timing advanced to factory specs (24 degrees BTDC), at highway speeds with the A/C on full blast on a hot day, the engine doesn't ping be"h.
Probably the most common cause of pinging is overheating, that's been my experience.
