What do you think of this method of valve adjustment?
I know this topic has been beaten to death and I've looked into every method. But I thought this was interesting. What do you think?
The only issue I see is, he is doing it with the lifters dry. What would be the impact if your lifters were full of oil. Like if you were just replacing rocker arms or something?
Skip to 7:30. He talks a lot.

That’s how I did hydraulic sbc’s For many years. Matter of fact, I just did a sbc last fall, used this method. It worked great because the valvetrain was adjustable. That’s the difference from today’s LS/LT stuff...adjustable vs. non-adjustable valvetrain.

So would this method work on the LT1s/LS1s from 93-02? Are there any issues with the fact that most of us working on them probably have oil in the lifters already?
And I would assume this would work with roller rockers just the same, correct?

You can use a method like that for the 92-97 LT1 since it has adjustable rockers, but not the 97-up LS1 which of course does not.
Yes, the adjustment process works the same with roller rockers. Play is play (or lack of it) no matter what the pivot method is.
No, oil in the lifters makes no difference.

Did not know that the LS1 didn't have adjustable rockers like the LT1. I learned something today. Would it be useful for a mod to move this to the lt1 section then?

Yes that's fool proof when your engine is on the stand and you have new lifters. Otherwise method 1 is quick and easy, pumped up or not. http://shbox.com/1/4th_gen_tech2.html#adjust_valves

It seems like there is a ton of disagreement on every aspect of this process which is whats got me so confused that I'm spending hours on youtube making sure I get it right hah

I NEVER do the spin method. Or the sequence in the video
EOIC do it per cyl. rotate engine by hand. Lifters pre-soaked before install
IMHO you are at zero lash when there is no more UP/DOWN movement of PR. Resistance in spinning you blew past zero lash at least a 1/4 turn ago

Yup. EOIC is what I posted above. If you use spin, especially when doing lifters that have oil on them, you can be too tight. I've never seen (or heard) of someone doing lash in the way this guy features.
