None of those things you mentioned are relevant, except maybe just to poorly manufactured kits back in the 1970s
Propane systems will only burn hotter if they are drastically under-fueled but these systems they sell now will blend and meter fuel plus propane, acting as octane enhancement (propane is 120) and cheaper fuel. The tanks they usually take out a spare tire and have tanks that fit in their place.
I'm a heavy equipment mechanic, worked propane forklifts, the engines would last over 8000 hours without rebuilds, virtually no wear on the cylinder walls or valve seats. Propane burns very clean, and 500 hour oil changes are normal and you don't see any darkening of the oil either.
The real argument against propane is the recovery of your installation costs with fuel savings and inconvenience factor of getting / filling propane
