Modern Cylinder Head

I can tell you why i would have used modern before Jeff passed.
I'm from california. There are lots of good machine shops, and I'm sure good porters here. But, I'll bet 85% of their business is chevy, and another 10% ford. There is a nationally known mopar shop within easy driving distance, and I have used him before, very pleased with his work, but, he ports by hand, and I don't want to pay for all the hours a hand port job must cost.
Therefore, I'm looking for a good cnc program for MY heads, 2nd version maxwedge victors. I want someone who knows, and cares about the differences between first and second gen, max and regular port, stealth,rpm, victor,trick flow, or pro maxx. Modern had those programs and the reputation for good specific mopar work. It's a shame that Jeff's brother has run into trouble maintaining that reputation.
(As an aside, I would SURELY have bought the trick flow 270s, but not even the tf240s existed when I bought my victors.)

This is where the difference lies... and I support @331MP in his thinking. Unfortunately, times have migrated into forcing racers to CNC prepared parts.

@LO23M8B also makes a COMPLETELY valid point concerning the Stock, Super Stock guys.
In fact, I have a anecdotal story that is hand in glove...
20 years ago, there was a local guy here (friend A) that had aspirations in running a 440 6Bbl in SS. Beings he was friends with another local guy, who campaigns a shivi in SS (never qualifies in the top 40 at national events) and runs a business porting heads, it was a natural to use him.
My friend gets his heads back (906s of coarse), and asks, 'how do they flow?'... 'don't worry about it' he reponds, '.....they flow good'. They did look 'ok', but I didn't like the VJ.
Naturally, not being satisfied with that answer, friend A takes said heads to friend B and throws them on the bench and found numbers that would probably never got him TO the national index, much-less BELOW the index.
Lesson learned, and the job had to be re-done.
