I have never used the lead additives in this car so I am just putting the question out since I was asked last week if I did or not. I am concerned thats all.
Tks for your input guys.

lou,
those additives you see at the local parts stores really aren't lead additives. if you read the fine print they are substitutes, or octane boosters.
if your running a motor with factory iron heads, you should be concerned if the valve seats have been changed to accommodate for unleaded fuel.
you could cause valves to recess into the seats if the heads still retain the original seats.
running premium may be all you need for octane, but the long term effects of the valve seats is the issue.
