Slant 6 HEI

Anyone ever see what the Australians used to do with the Slant 6? They used to take two Hemi heads and gut the alternate ends off, weld them together to firm a single inline 6 head, and bolt it on. They raced them, ran excellent.

Dave, do you have any documentation of this? If so please post. I have been racing slant sixes for about 40+ years. There has been much discussion, about "hybrid heads", but nothing verified. Granted I don't know everything, and am willing to keep learning. I do know for a fact, this has been done for the Ford and GM inline six.
