So I pulled my spare cylinder head out to get it ready to replace my current head, which has a few smashed valve stem, and I've got some rust on the hardened bearing surface.

All I've done so far is try wiping it away with a clean rag. Is there a good way to clean this up? There is some surface rust inside where the rocker shaft lives too. Salvageable? I have more cam holders (in my parts engines) I could use if I need to.

Are the top end parts mated? What I mean is do they wear together or can I just mix and match whatever is usable?

May I make a suggestion, I would try a scotch pad with wd40 to remove the rust.

I clean up a lot of rust with 000 steel wool and mineral spirits.
Works good on chrome, wheels and most anything needing cleaned.

Gonna take a lot of steel wool to clean up my avatar bike. But it runs really well dirty and rusty.

A little elbow grease with a green scrubber and acetone got them cleaned right up. Plastigauge and permatex are on the way, still need to order some moly lube for reassembly.
