Sanders 565 that is in his mustang is the single most impressive mopar engine running.

For that car to run that fast n/a is something to talk about. I don't think you can really call it a 600-13 head per se because of the amount of work that went into them. But you can now call Indy and buy castings. Send them to Goodwin and have them ported Don't know what to call them but in my opinion they are the baddest wedge Mopar head period and they make more power then any predator I've ever seen The guys at Best Machine have taken a great set of heads and put them to good use.
