Head Identification

[398HBX]

Need help IDing some SB Chevy Heads. I recently pulled the engine out of my 1986 3/4T, 4x4, K20 Suburban. I sold the block to a guy here at work. I told him that I still wanted the heads, intake, etc. Once he got it home, he decided that he anted to keep the heads, intake etc. I'm ok with that, I don't really need them. I just want to know what I getting rid of before I do. You never know, they could be as common as dirt or a rare jewel. We did not pull the valve covers off so I do not know the casting number. The casting mark on the outside end of the heads is Three vertical bars, all the same height. It is not a camel hump, or or of the other common casting marks that I have seen on Chevy heads. Anyone seen something like this? Any help is appreciated.
