help to identify a few parts
 

bought a motor already disassembled some time ago, coming down home stretch with the rebuild, have a few parts / bolts that i cannot identify.
First is (4) small aluminum pins, and second is (4) M12 bolts with thick aluminum spacer. After searching for an hour or so in parts lists, figured I'd ask the experts. Thanks in advance.

The 4 pins look like cam tower spray bar plugs. Look at the ends of your cam towers. Or they could be plugs for the engine case oil galleys. Not sure about the bolts.

Thanks green 993, the aluminum plugs are for cam housings, I tapped these out for easy removal, forgot about that. If anybody needs these drop me a line, can have them free.
