Generally I have not used a lead substitute additive and have never had a problem with knock/ping. The engine was rebuilt in '78 at 100k but the heads were not. I did have the heads done at about 120K. The odometer is now at 160k and counting. I do now use STP lead substitute but there still has been no problem and it runs great.
