With juice lifters, I have always had good results backing off the rocker stud, with the engine running, to the clack, then tightening so the clack just goes away. The rockers always worked well that way.
With these rockers, they are 1.52 Magnum Rockers. The rocker can be damaged by excessive lash during adjustment. Since I have never adjusted rockers the "new" way I was severly confused by the approach.
Tech1 really sent a good tutorial that helped explain the actual mechanics of juice rockers. I have found out, there are some subtle differences between the type I learned on, and the new ones.
Once the Magnums are broken in, and have a few miles on them, then if it is neccessary I can splash set them. I do have a set of spray deflectors. I have gotten used to working on a cooler engine however. I find it is easier to do complicated things on a cool engine than when every hose, metal part, and especially the manifold burns when bumped into.
Less noise, less fan wind, fewer people who just seem to come out of nowhere and that is the time to talk about something that has nothing to do with the engine.
