Dan said, "It will be a great day when 100NL (no lead) is available and the lead problem with valves and plugs, is also removed from the equation."
About three years ago I re-did the heads and valves on my GP 2180 at just under 500 hours (due to broken crappy re-used Chinese valve springs installed by RIMCO) and found no problems with lead build-up. It was very slight. I use mostly avgas and I run really, really lean. Problems with fouling or cylinder deposits are from running too rich.
