Preload is the pressure on your lifter. it is a hydraulic lifter so there is a cushion inside it. Preload is where there is enough pressure to not have the lifter's cushion all the way to the top of the lifter, but it is not bottomed out. If there is not enough preload you could have valve float...if there is too much preload, you will bottom out the lifter and tear it up. You have to find that happy medium

okay starting over again, I turn the crank until the INTAKE begins to CLOSE, i take the Exhaust rocker and and tighten the lock until while shaking the back of the rocker on the push rod until rocker is seated on the pushrod and no longer makes that "clicking noise" i then turn it 1/2 a turn and set it with the allen key, i can spin the push rod although it takes a little bit of effort, getting close?
OMFG. Who give a **** when the valve starts to close. Seriously.
Just make sure the lifter is on the base circle and adjust with the spin-drag method. The lifter will be bottomed out in the bore. Intake, exhaust, doesn't freakin' matter.
MAKE IT EASY ON YOURSELF.

Followed the Comp Cams Guide, Here is my step by step.... Step one: rotate engine until the Exhaust pushrod begins to raise/open, Stop rotation.
Pic->
then apply a some assembly lube to top of INTAKE push rod and place rocker back on... Pic->
Hand tighten the poly lock while rotating the pushrod until you feel the slightest bit of slack (we are now at zero lash)
Then turn the poly lock 1/2 a turn... pics->
Then set lock with allen key... Pic->

You have an unorthodox way of doing things. Do you not have a 5/8" box end wrench you can use?
Yeah it's a lot better when you have the right tools so you don't start messing up parts because you're lazy. But it sounds like you're doing it right now i would just keep my fingers crossed that you actually did everything else right
It's just that, for me, adjusting valves is one of those things where I like to feel what is going on. Can't do that so much with a clunky crescent wrench. Besides that using something like that can easily scuff up the tops of the rockers if you aren't careful. It's just one more thing to watch out for.

and it did just that lol whoops (scuff up the top) so through the confusion when doing exhaust side, can i do the same, rotate motor until intake side begins to lift/raise, then set lash on the exhaust side, or must i open the intake side fully and then once it starts to close set the lash for the exhaust side....
