AFAIK, the lead used to lubricate the valves or some such. It also
destroyed catalytics converters, so valves or the seats were
reengineered (hardened) to accomodate unleaded fuel.
I don't know if you will have problems with deposits or not.
Here in the USA the leaded fuel pump nozzles are larger so you'd have to
modify the fule inlet hole to accomodate them.
