Hi Temps = Lead fouling

Lean, aggressively.

Careful -- someone might think you mean "Lean forward, aggressively."

The points that Lance makes should make you wonder if the lead scavenging agent works at all. Because the combustion temps are always above the 900+ degree that is supposed to make it work. yet we still have lead fouling.

and that is my point, using less lead is more effective than temps in our attempt to avoid lead fouling.

900° C or 900° F?

As I noted earlier, 900° C is around 1,600° F.

Also keep in mid that the lead (or lead compounds) may condense as the gasses cool during the expansion of the power stroke and exhaust. They may not completely condense, so the scavenging compounds may well be working (albiet imperfectly).
