INSTALLATION INSTRUCTIONS
Please follow these instructions to ensure the proper operation of your T & D MACHINE
PRODUCTS Ford/Dart/TFS 302 Rocker Arm Assembly.
1. DETERMINE CORRECT STAND HEIGHT
Install the rocker stands on the cylinder head using the 7/16-14, 12 point attaching bolts. The
stands are marked with the part number on the lower right-hand corner. The stands should be
placed on the head so that the part numbers face the valve stem.
Note:
The Ford production 289/302 heads must have the stud holes drilled and re-tapped with 7/16-14
NC Threads.
Dart 302 heads must have the pushrod holes opened up to provide proper pushrod clearance.
For TFS “R” heads, the pedestals must be machined to provide a flat surface for the stand to sit
on. Tip the head in the ‘Y’ Axis (Short way on the head) until the rocker pad is level. Then cut the
pads equally until they are all cleaned up and same height to the deck surface in the ‘X’ axis. (Long
way on the head)
Remove a rocker arm from one of the shafts and place that shaft on a stand. Take the shaft height
gage supplied with the kit and place it on the valve stem as shown in Figure 1.
The gage should contact the top of the valve and the rocker shaft as shown in Figure 1 for
optimum rocker geometry.
