Just a question.
Could you mill the deck down just enough to reshape the chambers? I guess that would just add to the cost and not make budget sense for someone to do.

One can NOT CNC what is not there

I am going to equate this to small block Ford ProComp heads because that is where I can share actual CNC experiences.
I am a ProComp dealer and also a RHS dealer. Bare ProComp heads are about $500.00 less money per pair than the RHS.
The cheap A$$ street wienies just don't wish to pay the extra money for the better flowing, fitting, "out of the box" RHS head. Almost every one who walks through the door wanted to know if he could have the ProComp heads CNC'd and get a better flowing head in the end.
You simply can't talk sense to the 20 some year old who knows everything and has little money to spend.
To make a long story short ... I developed a CNC program for the 195cc ProComp heads.
Those idiots buy, the ProComp head and pay the extra $700.00 for the CNC work. I only work with bare heads in either case so the other parts and charges are the same.
The ProComp head now flows good, (not great), air but, for near the same amount of money outlay an RHS head of the same finished port size with hand "bowl porting" could have been had with only about 10% less maximum airflow; actually better down low.
However, now those customers can tell everyone they have CNC'd heads, as that is the major BUZZ word with the uninformed high performance enthusiast and they can all rave about what a good deal he got.
I have done a bunch of 'em and trying to talk sense to them just goes in one ear and out the other.
