They are blue print engines heads, what actual castings they are I don't know.
NO it is not "Ricks" Head. "Rick" still refuses to post a picture here of his head, so we are talking about to everyone else's head that they are posting trying to help "Rick" who for some unknown reason won't post the picture of hisThose are the AC delete bracket. They don’t use the long PS stud that you described in your first post. There should be 2 long bolts that thread directly into that bracket and do not go into the head.
I also assume that’s not a pic of your engine since I see Edelbrock heads in the pic.
