I believe that Vic Jr's are vertically centered too but the ports are more rectangular. I have a set available and can check if no one else knows.

Jim, I recall an older article in Second Strike that showed that the header bolt orientation on the Victor Jr's was actually either slightly lower or higher than the AFRs. In other words, the header would bolt up a 1/4" (or more?) up or down from one head vs. the other. This is what I'm trying to verify, as that would mess up alignment and force the use of a shim (at the collector flange) to angle the down pipes properly. An angled shim = another gasket = another opportunity for leaks.
