New cylinder head - what's in the box

Hi all,

I'm wondering if those who have replaced the cylinder head with a new one from Toyota could share more about what's in the box. The part I'm referencing is 11101-39725 which looks like it's just the cast aluminum head and doesn't include any camshaft components, any valve components, and, potentially, no spark plug tubes.

If tubes aren't included then what's their part number? The repair manual refers to the tubes as "spark plug tubes", but no parts show up on parts websites if you search with that as the keyword.
