I have numbers from my bench and your stage 6's, so it will be interesting to see how they compare side by side. IMO, what those 6's really had going for them was decent flow from pretty small port volume, which I feel is a good combo for moderate cube pump gas motors running in heavy-ish cars with closed exhaust systems.
Yeah, I have your #s for both my old Stage VIs and my Hughes CNC'd Victors. I expect the TFs will fall somewhere in between the two, as does their runner volumes.
Re: how small the port volume on those Stage VIs were (are): 213-215cc on the ones I measured (NOT including the RB intake spacers). The MCSA was, realistically, small-block sized, but on my 452 it was a happy combination.
