When an engine runs lean, that creates high combustion temperatures. Can cause pre-ignition that can do real nasty things, but if it did, you'd know it already. Can 'burn' valves, melt pistons (they are alluminum alloy), ect. Another reason to use the proper octane fuel. Many will burn the cheapest stuff they can pump. The lower the octane, the higher the combustion temp.
