4 valve 911 heads??

Hey...does any one know what became of the aftermarket 911 4 valve heads. The picture in Bruce's book calls the advantec?? I have to look again to be sure. I also rember seeing an article on them in European car magazine 10 to 15 years ago. Any one have info on this subject?? If I remember from that article some one bought the rights to the head and was in canada but more developement work was being done in germany. Was heat the issue...or some thing else?
