Why didn't they put induction hardened valves in engines when lead was used? COST. Lead prevented the problem of burned valves for 50,000 or so miles. On old engines, you got a carb and valve job at about that mileage where the head was pulled, the valves ground along with the valve seat and the carburator was rebuilt.
Thus endeth the lesson from the past from the old organic chemist.

Nice post Boomer!
Back in 1953 I had a new '53 Plymouth Flat-head Cast Iron I-6 about 100 HP stock plus Dual Carbs. high compression Aluminum Edmonds milled head, mallory dual point ign., equa-flow headers with twin Smitty's glass-packs, Larger clutch and rear tires (for gearing) and lowering blocks in the rear.
... At the time I drove a gasoline transport 18 wheeler. We were able to collect 130 octane av-gas from the discharge manifold between the time of loading and unloading the fuel. I would put the av-gas into the Plymouth along with some motor oil to protect the valves.
I did burn some valves once. I cold out drag and out run the poor stock power-pac V-8 Chevys even without the av-gas and make their owners cry.
Have a good one while you can still laugh about it.. Don S..
Laws such as the use of corn ethanol are driving up the cost of living (have you been to the grocery store lately) without driving up wages. This equates to a lower standard of living thanks to Agro-lobbyists and corrupt and/or ill-informed lawmakers
