Rory,
I knew that the manifold in the picture was not correct but did not know what it fit. I had a set of those heads for years and sold them about seven years ago to a local who was restoring his GTE. I compared them to a pair of CJ heads and other than a difference in the exhaust bolt pattern I could not see any difference. During machining of the head it appeared that they had machined the CJ exhaust pattern in them and then filled the holes that were not correct and redrilled them. If my memory does not fail me it was four or six holes per head.
