Trick flow heads use stud mount rockers on their heads.
Installing and Adjusting the Valvetrain
Place the proper length pushrods into the pushrod holes. Coat the base threads of the rocker studs with oil (do not use antiseize!), then put the guideplates on. When everything is lined up correctly, torque the studs to 55 ft.-lbs. (using motor oil). Place your rockers on the studs, and make sure they are centered side to side (see Figure 6). Adjust the valvetrain according to your cam maker's specifications. If you are using a hydraulic cam and no specs are available, turn the rocker arm adjusting nut 1/2 to 3/4 of a turn after zero lash. For mechanical cams, you must get the correct lash specification from the cam maker.
In either case, the simplest method of valve adjustment is to follow the firing order, turning the crankshaft a 1/4 turn between each cylinder. For example, turn the crankshaft until the first cylinder listed in the firing order is at the TDC position on the compression stroke. Both valves will be in the closed position. Adjust the valves as described above, then rotate the crank exactly 1/4 turn and repeat for the next cylinder in the firing order. For other methods, consult your shop manual.
