A lot of the racing gas is leaded for the octane boost so you could use some of their statistics if you'd like. They talk about deposit buildup in the O2 sensors and valve to valve-seat issues. It comes down to what he's willing to risk. Valves are more hardened now than they used to be, so on that front, it may not be that big of a deal. Personally, I've never done it so I'm only going on references from others.
