lead substitute/additive

[Silver R/T]

Schucks used to carry lead substitute/additive. I dont see it on their site, wouldn't be surprised if they pulled it off the shelves due to EPA. Anyone know what Im talking about? I suggested a bottle to a guy with Nova that has original motor/heads (without hardened valve seats)

I usually get mine at AutoZone.  They carry an additive and so does Advance Auto, NAPA and Pep boys.
