My machinist told me about these. They were an Austrailian company's casting, but they went bankrupt. Comp Cams bought em up and now have released the same heads through their Racing Head Service division.
Check out the flow numbers, the 180's cover the AFR 205 up to ".400, and the 215cc heads overtake the AFR 205 all the way to ".600 lift at half the cost ($697 bare pair irons, $997 alum bare). I'm picking up a set of their 200cc iron's once I get the bottom end of that new motor build
