Are the 1JZ valve adjustment specs the same as the 2JZGTE's?

I need the valve adjusment specs and procedure to the 1JZ, is the 2J specs the same?

Does anyone have this info, specs?

Yes. Same as the ones in the 2JZ manual.

^this. fwiw I usually run them on the tight side. Like .008 in .010 ex. Makes them all quiet and shit. And gives imaginary hp from more overlap.

I run the same specs and make sure you check them cold as well since those are spec when the head is cold.
