R3W7 Assembly
Here's another nice feature of the T&D rockers....their setup allows the use of a simple height gage that establishes, easily, the proper geometry of the rockers. They sell these gages, but they also give you a drawing in case you want to make your own. Since I didn't want to wait a week to get in a gage, I made one. This compares the height of the valve tip to the centerline of the rocker shaft, and they give you some basic math that allows you to know how much shim to use under the rocker shafts. In my case, with .680 lift, I will need about .100" of shim. Use less shim for higher lift. This is a good thing....it's an indicator that I could run around .800" lift without any machining, if I wanted!
