Hi Don,
IMHO you do not need to do anything to the head or even change the
valves to run satisfactorily on unleaded fuel for a very long time. The
general consensus seems to be that only small high revving engines which
are required to run for long periods at high throttle settings require
hardened valves and/or seats.

to have my head converted so I can use un-leaded gas is it true that I
only need to have the exaust valves replaced?my head seems in good shape
the car has about 75,000 is there anything else I should or could have
done to it while I have it of?
thanks for the help
