I'm not an engine guru, so what is the issue with 100LL fuel?

They used hardened seats and stainless steel valves with chrome plated
stems, plus hard tips with bronze guides so nothing would stick and
freeze up on them using the 100 LL. Tom thinks that was all an over
kill but I have no idea. So, you'll just have to make your own
conclusions.

The other issue is that in conversions that use oxygen sensors, they wipe
out the sensor, in a fairly short period of time.
