To adjust lifters on 216-235-261. Here is the correct procedure.
First-
Your valves are laid out this way- from front to back-
#1 exhaust,
#1 intake
#2 intake,
#2 exhaust
#3 exhaust,
#3 intake
#4 intake,
#4 exhaust
#5 exhaust,
#5 intake
#6 intake,
#6 exhaust

This procedure can be used on either Hydraulic or Solid lifters. Just know which kind of lifters you have for final adjustment.
Turn the crank (by hand) until #2 cylinder intake valve (look above- it is the third rocker back from front) is observed to start opening (that means the rocker is pushing the valve down and open). Now turn the engine slowly and notice that #1 cylinder exhaust (first rocker)valve will also start to open. Continue cranking until #2 cylinder's intake valve is wide open, AND then notice that #1 exhaust valve is also coming to the wide open position. (#1 exhaust valve lags a little behind #2 intake valve) Continue turning (slowly) until both valves are wide open.
With these two valves wide open adjust:
Solids: intake-.006. exhaust-..013 (special note: if this is 1 1/2-2 ton truck exhaust is .020)
Hydraulics: adjust until just touching and no or very little wiggle of rocker can be felt.
Adjust:
#1 cylinder intake
#2 " exhaust
#3 " both
#5 " intake
#6 " exhaust

Now turn the crankshaft one full turn until #5 cylinder intake is observed to start open. Lagging behind will be #6 cylinder exhaust. Continue turning the crank until both of these valves are wide open and then adjust:

#1 cylinder exhaust
#2 " intake
#4 " both
#5 " exhaust
#6 " intake

Now you engine will be ready to start and let it idle for 30 minutes till completely warm and do the final adjustment.

It has been brought to my attention that I didn't give the final adjust for hydraulics- Tighten down until no noise is heard (use a section of hose to your ear and to the tappet if needed) then tighten one(1) complete turn.

If you don't know whether you have solids or hydraulics- Pull the rocker cover, loosen one rocker, pull the push rod, drop the side cover off, pull that lifter. Now take it to a machinist or mechanic and ask him which it is. OR, once you have the lifter in hand look to see if it has a hole in the cup (top) end and will push down in the center, if it does it is hydraulic if not it is solid.

Thank you Oly.

Thanks OLY!

Thanks, Oly... that was going to be my next question.

I believe there is a typo in Oly's message. I don't own one to know for sure, but .0006 sounds too tight for clearance on the intakes with solid lifters. I would imagine you meant .006, easy mistake to make. I just don't want anyone to adjust their valves wrong and have to go back in there to change them.

Good eye, '65. I missed that one the first time around. I like to think I'd caught the mistake as I was looking for the .0006" feeler gauge.

Yes I missed that bit of a typo. but I could have been thinking I was rebuilding a turbo jet engine-LOL It is six thousandths, not six ten-thousandths.

Thanks Oly!
That's one for the printer...
