Highest flowing sbm heads?

What happened to the Airwolf head? Might not be the entirely correct name, but I remember seeing a magazine test of a build (I know, suspect already) and I remember the motor being over 600 hp. No idea on the specifics, but I kind of remember looking them up and they were by Dr. J?

Did they get a different label? Or were they "vaporware"?

Not tossing them out there as an option (I have no input on that topic), just a curiosity.

Apparently they were pretty good heads, I knew I guy who got them early on. Apparently air wolf went out of business or something along those lines so I don’t believe they are available anymore

Ahhhh….. DrJ! Can’t remember that guys name (Bruce Mulvey??), but he took money and disappeared. There were a couple guys on moparts that got burned. the late Mopar Billy (Gebhardt) finally got a set and they’re probably still on his old white dragweek car. It took some time and he thought he’d been had, but they finally materialized.
