You can add a lead additive if you want. Or not.

I'm sorry, i cant resist this one.

Education incoming: In the center of the webpage, below the Expedition Imports ad, is the search button.

No additive is required, especially in a 1980's model as leaded fuel was already phased out.
Most of the lead substitutues just cause nasty deposits on the valves.
I have yet to find a "soft valve seat" in any Pinz head and I have rebuilt many of them.
