What would sludge buildup in the rocker box have to do with lash setting?
And I went with positive seals, I did ask about clearance between the tips of those and the bottom of retainers, we talked about what my gross lift would be, when I picked up the head they said that the took care of that. I don't know what they set spring installed height to, can check when I get home from work. I'm thinking they went with stock specs for an unmodified slant head, I did provide stock 318 springs for them to put on/which I see that they did.
