Default V5 STi Valve Clearance?

Hi,
New here. I've got a set of v5 sti heads for a friend's car I'm helping him with and I wanted to make sure the valves were in spec.
First, do these heads have the shim under buckets, or are they shimless buckets? I havnt taken them apart yet, so I dont know.
But my main question is about the valve clearance.
I measured them and got .006" on the intakes and .008" on the exhaust.
The only specs I can find on subaru heads call for .007-.009" on the intake and .009-.011" on the exhaust. But I dont know if that applies to these heads as well. I'm a VW guy.
Thanks for any help you guys can offer.
Heres a picture of a friend's "oops" for fun

Yes they are the under bucket shims, and those clearences look fine to me.

Thanks for the info on the shims.
Do you have the actual specs and tolerances for the valve clearances?
