Ok I'm setting my valve lash and have read up on NASIOC and found some threads on figuring out bucket size. Any body have any tips. Also I have 06 d25 heads. Correct me if I'm wrong.
Intake .20+\-.02mm. (.0079+\-.0008in)
Exhaust. .35+\-.02mm. (.0138+\-.0008in)
My micrometer measures IN so ill be using that. Thx

I use Ken gilbert and my Oem Subaru Spec manuel, but what your stated looks familiar to me: You can request what ever you need and they will post it

There is a zip for the 2006 but it is pretty close to the same, or the same

Another question. At what point is a bucket out of spec. I couldn't find anything in the FSM. Most of my buckets are measuring one size down. Some as much as 4 sizes down. I don't think I want to use anything that warn out.

I got a copy from mechie and I cross it with the 06 ken Gilbert manual.

I would get the clearances spot on, if to tight the valves will not close all the way and to loose the buckets and other things will get worn out fast. You might need new buckets and other stuff if it is out of spec. I always build exactly to tolerance and hav no issues.
