Leaded/Unleaded

[bruce plecan]

Does anyone know what they do for O2 sensors in
places where they sell just leaded.  I've heard that
it's the same sensor, and some folks run the leaded
(with no cat), and don't have much of a problem.

Seems on some race car stuff they don't last very
long, but is that do to high Exhaust Gas Temps?,
any one, care to comment?.

Then rumor has it that using a heated O2 sensor
makes them much more livable on leaded.
