12. Crane Cams provides an instruction sheet that tells best how to install the guideplates, adjusting nuts, and set screws. You'll need to find TDC (top dead center) at 0 degrees, and adjust each rocker individually in a specific order. This is an in-depth process, and if you don't feel comfortable doing it yourself, please consult a professional. Luckily for us, Larry Garcia at Jeeps R Us has done this many times before.
