Casting variances. |

I suspect I may know what the "angle" factor is that these people are talking about. I believe the persons making the claim may be observing core shift, as I can see how the positioning could vary notably, based on the cut of the head.
All I can say is they look identical to me. Also, I don't believe Ford put any kinda oddball engineering effort into making the 428CJ head runners flow. They simply used castings that were sitting on the shelf (remember - CJ heads are cast to fit normal FE valves and gotta be dressed out to fit CJ sized valves) and happened to pick only the good stuff this time.
