Those numbers don't seem low to me for a stalled auto and 278's.
You said professionally ported by you, does that mean you've done extensive research and development in finding the perfect flow patterns, or that you have a machine that is programmed to have as close to perfect symmetrical bowl patterns as possible, or does that mean you've ported heads before and thought you'd do your modular set because "How different could it be"?
Do you port heads for a living? If not then they are not professionally ported.
If yes, then Ok.

No your right I don’t do it for a living but my skill makes me more then ordinary. I’m not a professional and I’m not saying its perfect I was more or less being sarcastic. I've ported anything from my 2v to a iron set of Pontiac heads. I've never ran a flow test and I have never established what real power I have accomplished. I’m an amateur but the research and time is there.

I think your numbers are good and although I can't begin to understand/explain why stall's and dynos don't mix every well, I agree with what the other guy said, As long as it performs well, that's all that matters.

If you don't have a flowbench, there's about a 90% chance that your heads are hurting you. As stated earlier, 4.6's are very very very picky about velocity, and home porting on the exhaust side especially kills these heads.
