header bolts?

hey guys, i've jsut finished putting the head gaskets on my 94 stang and i was putting the header bolts back in and most of 'em are threaded on both ends, sorta like brackets are supposed to attach to them or soemthing but theres no brackets to be attached...anyone out there know what i'm talking about? if ya do let me know what their there for. thanx for the help.

Mine had those brackets, but they wouldn't fit over my new pipes... They were on the front of the engine on the drivers side and the rear on the passengers side... By the way they look, I'm guessing they are used to hook the engine to a hoist so you can pull it out... But, like I said, they wouldn't fit over my header pipes (they fit over stock.) If you want a picture, I can take one...

I've seen the brackets for the transmission fluid tube (for automatics), and the oil dipstick tube attached to the header bolts.
