How do I tell a set of Gen II heads from others?

[red01GTS]

I think that I have found a nice pair of bare Gen II heads that are lightly used (under 15K miles).

It occured to me that I am not sure how to tell if they are indeed Gen II heads. Searched the forum and really could not answer my question.

There are several mold marks on the front of the heads.

I am hoping to pick up a pair to send to Gred Good early next year. This way I will still be able to drive my car, no down time with the heads off.

Thanks for any help.

send a pic of them to GegGood. I assume He would be able to tell the diff
