not X heads and not J heads...what are they?

yeah, I knew I could look at the casting numbers and find out what they are in my books. I don't have it home yet, and didn't have time to pull a valve cover. going back to get it tomarrow. I was just seeing if anyone may have seen the "wierd" raised square casting in place of the X or J, and knew what it was off the top of their head.

Tony, are you saying that info you posted should be what that casting will turn out to be?

I have a new set of Hughes prepped edelbrock heads that I would use on it if I ever did anything with it, but I just was wondering what heads I was ending up with.

Acting like I didn't get a good enough deal, and the heads have to be super duper prepped X heads or something for me to be able to come out to the good, lol!
