Yes, the ad is old and was back when I originally released these heads. This is a completely different animal so to speak. As for how well they work on a 360, I can't think of anyone that has done it at this point but, I can't keep up with everyone's builds either. I don't have any reason to believe they wouldn't work very well but, I don't have any track results to prove that either. You can PM me here or on my personal facebook page.
Thanks,
Rod
