Couple of quick points...

1) The 454 tune is, of course, dumping in WAY more fuel in a lot of areas, so it makes sense that the backfire is worse with that tune.

2) Looks like the commanded timing...

Rang, can you post up screenshots of both your 401 fuel table and the 454 fuel table for us to look at?

Probably not related to your issue, but how tight is the fit between the actual PCV valve and the rubber grommet on the intake manifold? Sometimes they loosen up and induce a vacuum...

Very good. I was going to suggest looking at your tach input very closely and seeing if you are getting the correct counts just before, and during, the backfire. That's always step #1. Sometimes a...

You know where I stand on this from that other thread, lol. Few engines are cooler than a Jeep Tornado, especially for that "old truck" feel.

There are smaller TBI units that will work on the 258. Or like DarkMonohue suggested, just go factory MPFI. There are a lot of better options than fiddling with carburetors.

You said you've rebuilt several carbs before, so EFI isn't all that more...
