As far as your rockers, try it this way:
1) Install one rocker arm at a time by inserting the 5/16" bolt through the top of the rocker arm, MAKING SURE THAT THE FLAT SIDE OF THE FULCRUM IS FACING THE BOLT HEAD. After this is done, slide the pedestal onto the bolt with the curved area of the saddle contacting the rounded side of the fulcrum. Next, slide the guide channel onto the bolt with the raised edge facing up toward the rocker arm, then loosely thread the bolt into the head, while making sure that the pedestal is in the channel and the saddle is in the correct location on the fulcrum. Install all 16, and snug down the bolts by hand.
2) Rotate the engine until the balancer reads TDC on the compression stroke.
3) Check the rotor in the distributor, and verify that it is pointing at the #1 wire on the cap. If it's not, rotate the engine 360 degrees.
4) With a 1/4" drive ratchet, tighten the following rockers until you can no longer rotate the pushrod:
Cylinder #1 intake and exhaust,
Cylinder #3 exhaust,
Cylinder #4 intake,
Cylinder #7 exhaust,
Cylinder #8 intake.
5) Now torque each of those to 20 ft.lbs.
6) Rotate the engine 360 degrees, so the balancer reads TDC again.
7) With a 1/4" ratchet, tighten these rockers (again, to zero lash):
Cylinder #3 intake,
Cylinder #2 exhaust,
Cylinder #7 intake,
Cylinder #6 exhaust.
8) Now torque each of those to 20 ft.lbs.
9) Rotate the engine 90 degrees, and with the ratchet, tighten to zero lash on these rockers:
Cylinder #2 intake
Cylinder #4 exhaust
Cylinder #5 intake and exhaust
Cylinder #6 intake
Cylinder #8 exhaust
10) Now torque each of those to 20 ft.lbs.
***If it takes more than a full turn to reach 20 ft.lbs. torque, after you have reached zero lash, you're gonna need shims.
Take care,
