That is definitely a wide open vent. Here is a chart I collected from somewhere (ebay probably) giving some crosses to the cap that is supposed to fit a 51-6 Packard. It adds a few other mfgs you could see if they offer something different.
The fill pipe on the repro tank does have a more gradual and lower slope so maybe that is making a difference.
Danchuk has a repro cap that is supposed to be identical to the original Chevy cap which according to the chart would fit.
The vent on that cap looks like it might also go out the top thru the square piece but maybe the length of the hole thru the square is enough to prevent the leak. Not sure how a single thru hole could be called a complex venting system so maybe it is more involved and there is an indirect path or vent actually stays under the shell.
