Ken,

Here's how the shop manual says to do it:

With #1 at TDC, adjust: 

#1 intake, #1 exhaust, #3 intake, #5 exhaust #4 exhaust, and #6 intake 

rotate crank one full revolution (#2 at TDC) and adjust: 

#3 exhaust, #5 intake, #2 intake, #2 exhaust, #4 intake, and #6 exhaust 

The shop manual says to turn in 1 turn after pushrod endplay is gone. I
think that today's new lifters only require 1/4 to 1/2 turn instead on the
manual's suggested 1 turn. The pushrod may still be able to be twisted
(rotated about its linear axis) before the extra turn but will not move in
and out. Quite often, people think that this means you can't budge the push
rod, but that is wrong. It may still be rotated..just the endplay is
removed. If in doubt, use a 0.001" feeler gauge between rocker arm and valve
stem and tighten until there is drag when removing the gauge. This would be
zero lash. Then do the 1/2 turn and you're done.

Good luck,
