Default quick question about a head rebuild

My 02 wrx valves got all bent, engine is out and I am beginning the teardown, heads will need a rebuild and I can't seem to find a complete list of the components I will need for the rebuild. I am a noob, first engine pull ever. I am going to have a shop rebuild and machine it but I need to buy the parts.

I know I will need...
valves
shims
buckets
springs
retainers

Can anyone add to the list? Any help is appreciated.

better check and replace the valve guides.

use OEM valve seals too, and new keepers.

PM me if you have questions.

Heads should be pressure tested, and I ultrasonic clean them.

You may want to ask, not tell (they don't like that) your machine shop to be sure to remove the oil galley plugs in the heads. They come out fairly easily once the heads are hot from the cleaning tank or spray wash cabinet.
