As A7 blocks pre date the introduction of leaded petrol by many many years, why did valve seats not erode "in the day".....? 
As for ethanol I recall that "Discol" I think it was claimed to have a significant ethanol content and no one worried about what it did! 
Mind you with a gravity tank is it supposed to attack steel brass, copper, zinc and solder....?
