LLT cylinder head help

[Troyb]

Hi all, go easy on me as it's my first post and this problem may has been covered before.
I am build a SV6 LLT engine and have stripped left hand cylinder head and was cleaning in a kero tank when a small copper tube fell out from somewhere and need help to know where it belongs.

Thanks Troy

Looks like a dowel to locate the cylinder head on the block.

Moved to the V6 section.

If one of the faces looks like it's broken off something, it could be part of one of the valve guides. Look for any holes that it will fit in and see if you can identify other ones.
