Adjusting Lashing on RR's

[PKRWUD]

As far as your rockers, try it this way:

1) Install all 16, and snug down the nuts 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 tighten each of those 3/4 of a turn.

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 tighten each of those 3/4 of a turn.

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 tighten each of those 3/4 of a turn.


Take care,
