If your going with Valvoline use VR1 it has a good zinc package. I use 20 -50 in my 565. I was using Amalie 20 50 but I did have some unusal wear on 6 intake rocker. They don't have any info posted on zinc content. I finally got it out of them 750ppm. The VR1 is 1,700ppm. Lucas has one at 3,000ppm. Since everything else in my motor was in good shape I am trying VR1 next as a change.
