All the stuff you said is nearly impossible on a stock 1996+ with stock injectors.
You have to hold 15.5:1 Afr at wot for nearly a minute on aluminum motors.
Most cars are in limp mode with a cel which simply disallows your situation.
Myself and frank along with hundred of others on the e85 forums have a decade or more experience each burning it and the only cases I am aware of that holed a piston were custom motors.
Find someone who has burned their valves due to e85 and post it here, so we can dissect what he did wrong.
