This is how I adjusted my rockers and it worked perfect. This is the method for roller rockers. I guy with the screen name PKRWUD gave this info to me and it worked the first try. If I can do it anybody can do it. And I can't explain why to use a 1/4" ratchet.


1) Install all 16, and start the bolts, but don't tighten them.

2) Rotate the engine until the balancer reads TDC.

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. If the
distributor is out of the engine, or is off, you can find TDC on the
compression stroke by pulling the #1 spark plug, wadding up a paper towel as
small as you can, and jam it into the spark plug hole tightly. Rotate the
engine until the paper towel pops out. Then rotate it until the TDC mark and
the zero degree mark meet (the TDC mark should be very close when the paper
pops out). This is TDC on the compression stroke for the #1 cylinder.

4) With a 1/4" drive ratchet, tighten the following rockers until the rocker
tip is just snug against the valve:
Cylinder #1 intake and exhaust,
Cylinder #3 exhaust,
Cylinder #4 intake,
Cylinder #7 exhaust,
Cylinder #8 intake.

5) Now slowly tighten each of those with a torque wrench to 25 pounds. If
the bolt turns less than a quarter of a turn, you need longer pushrods. If
the bolt turns more than 1 full turn, you have to add shims until it can be
torqued to 25 pounds in the range of 1/4 to 1 full turn.

6) Rotate the engine 360 degrees, so the balancer reads TDC again.

7) With a 1/4" ratchet, tighten these rockers until the rocker tip is just
snug against the valve:
Cylinder #3 intake,
Cylinder #2 exhaust,
Cylinder #7 intake,
Cylinder #6 exhaust.

8) Tighten each of those to 25 pounds of torque, just like before.

9) Rotate the engine 90 degrees, and with the ratchet, tighten these rockers
until the rocker tip is just snug against the valve:
Cylinder #2 intake
Cylinder #4 exhaust
Cylinder #5 intake and exhaust
Cylinder #6 intake
Cylinder #8 exhaust

10) Tighten each of those to 25 pounds of torque, just like before.


That's it!
