Corky,

Bud just overhauled the heads on his Ford because it sat for a number of
years in Florida. He has been using 100LL almost exclusively. The head
shop found heavy lead deposits on the valves which they found difficult to
remove (probably forgotten how). It may be that TCP or similar product is
necessary in our Fords if we run avgas all the time.

Well, there you a actual experience trumps conjecture most of the
time. I humbly bow to the superior information.

Ron, as to the oxygen sensor, some very clever people have managed to
fake out the system by sending a trace voltage to the computer making
it think the sensor is working. Don't know how the computer then
knows how to adjust for all conditions when the signal to the computer
from the O2 sensor is fake though.

Having to fake out the computer, along with having to depend on the
single source for your ignition AND timing is why I've chosen not to
go that way. Well, that and not wanting to pay for injection capable
heads and the fuel pump, rails, plumbing, injectors etc etc for a fuel
injection system.
