R3W7 Assembly
So I spaced up the shaft assembly .100". The shims go between the head and the black anodized rocker support, not under the round shaft itself, so it's easy to make a shim out of flat stock. The pattern looks good. The "IN" means the side that is toward the intake manifold. This is what T&D says they want to see for roller contact....a slight offset toward the intake side when the valve is closed. As it opens, it moves a little toward the exhaust side, then at half lift it begins to move back toward the intake side. The pattern shown is with right around the .680 lift I plan to use.
