Ahhh Mark, now you're teasing me. Since you mentioned your mass flow install worked well for you, I was most interested in LSA and timing of cam events. As Dan mentions, there is a point where you will never be able to reconcile the BSFC of your injector settings, the O2 reading from a broadband sensor, and the lb/min of air indicated by the mass flow sensor. You must not be there yet. Those specs are right in line with the 392 crate kit below but it is not any more revealing.

Seems about right. The engine in my car at the moment has a fairly tame hydro roller with similar duration and lift and and made 536 ft-lb @ 4750 rpm and 518 HP at 5250 rpm at the flywheel. All North of 500 ft-lbs between 3 krpm and 5.5 krpm. It has BF301 heads which with this cam is barely scratching their potential, but they do flow well. It's a 427 CI and the intake isn't the best match to the combination (open plenum single plane spider with Holley 750HP series) but it's a nice running street motor with good street manners.
However, as we all know, it's never enough. -More to come.
Hopefully this is useful discussion for Michael. If not, apologies for the thread drift.
Best,
