My buddy has these heads that have been sitting in his garage. We're trying to figure out what they go to so we can stick them on craigslist.
There are several numbers i've found on them, 60260, 2643675-24, some of the others are hard to make out. Here are the pics

 

I google'd some pictures of some common V8 heads. Looks like its a Chrysler 318/360 head, but I'm not sure of what year(s)

EDIT: Checked some more with allpar.com, it looks like this may be an early Chrysler A series 318 head, or perhaps from some other A series engine.

 

I to believe these to be a Mopar LA series 318/360 heads.I think they ran that engine series from 1968-2002. I don't know the specific years of the heads you have.
