Hi Ricardo
Good morning!
So the 8 Stop procedure is all about setting the valves, right?
Well....... it is a misnomer to think that we adjust valves. There is no valve adjustment nor are there any lifters.
(these are carry-over terms from years past)
Your hydraulic cam "followers" incorporate a hydraulic plunger within the body of the follower.
This plunger rides on a cushion of pressurized engine oil.
The plunger (aka piston) has a check valve underneath it to prevent oil leakage during camshaft lift.
The rocker arm tip is to have NO slack between itself and the valve stem while the camshaft lobe is at bottom of the base circle.
When we have removed the slack, this is ZERO valve lash.
Once ZERO lash has been achieved (cam lobe at bottom circle), we give the rocker arm stud nut an additional fraction of one turn (it may be 1/4 turn, it may be 1/2 turn or it may be 3/4 turn, depending on what the OEM specs call for)
This additional fraction of a turn sets the push rod into the cup of the cam follower plunger.
The cup depresses the plunger to a prescribed depth.
Each of these adjustments must be made while each cam lobe is at the bottom of base circle. The 8 stop procedure ensures that each pair of cam lobes (1 intake/1 exhaust) are at bottom of base circle.
Each plunger has a potential travel of .100" to .130", or so.
The goal is to place the hydraulic plunger at/near a 1/2 way point between bottoming out and topping out.
I did not do the 8 stop, I followed the YouTube "A1 Auto" made (

These are the guys who get people in trouble.
I would NEVER suggest using the 2 or 3 stop procedure.
TDC: (setting)
Intake 1,2,5,7
Exaust 1,3,4,8
Then move 360 to TDC exaust (setting)
Intake 3,4,6,8
Exaust 2,5,7
You do not find this method good, ??
NO! It is NOT good! At best, it is a lazy man's short cut!
, should I redo it the 8 stop way?
You do what you want to..... if it was ME, yes!
If the engine will fire up (witch I hope it will), I will set the ignition timing.
1. Block the vacuum hose to the carburetor
There should be NO vacuum hose to the carburetor.
2. Rotate the distributor until my timing gun, show the mark at TDC -10degree
Or do you have a different (not to complicated)
procedure here to?
Bring the crankshaft around to #1 TDC C/S.
With the ignition ON, and with a good spark plug inserted into #1 plug wire (plug body must make good metal contact), rotate the distributor CCW until you see a spark event.
Gently lock it down.
Start engine and set BASE advance.
