Actually LESS likely to burn a valve on AV gas, as it has/had lead. Newer stellite valve seats were needed to run no-lead. Most likely early cars ran to demise running no-lead.
Chevy Power Manual RECOMMENDS 100-130 octane AV as fuel, for high perf. motors.
I ran/run it in my 68 Camaro (450Hp small block 12:1 compression) , just can't pull up to the pumps to fill up anymore, and leave my mark (positraction) on the runway when leaving......
P.S. my old gas goes in a 1940 Ford tractor, has a prefilter, water sep sediment bowl, inline filter (add-on) and screen before carb: at 6.5:1 comp. will run about any swill it is fed including old two stroke mix. Water will sep. out and can be discarded
