Lifter preload?
Lifter preload? So what is the correct lifter preload with YT rockers? Some say zero lash then 1/4 to 1/2 turn and then 22 ftlb. Others say zero lash then 1 and 1/2 to 2 turns then 22 ftlb. Which is it? 
Re: Lifter preload? well, it depends very much on which lifters you are using.
If you are using stock lifters, they like more preload. I personally would not go less than about 3/4 of a turn on stock lifters, otherwise I would expect some noise. 1 1/2-2 turns would be fine, I think, but a little more than you need.
For Comp R lifters, I would go with approximately 1/4-1/2 of a turn.

Re: Lifter preload? Yella Tera's are non adjustable. You need shims or you need to buy the right size push rods! I think stock lifters like to have around .030-.050 preload and Comp R's like .010...

Verdad Gallardo Re: Lifter preload? you have to either put shims under the rocker arm or change the length of the pushrod in order to get the preload right, maintain the 22lbft necessary to keep the rocker there, and keep a reasonable semblance of valvetrain geometry.
