I think the term is "symmetrical port" heads. I applaud your enthusiasm and wish you well. Hopefully you are past the "idea" stage and have some kind of idea what the process will cost, from development to core boxes to a finished product. That, combined with the reality of how many sets you can actually sell will set your price point, not goodwill towards your fellow mopar racer.
I have ties with a major cylinder head manufacturer and cannot convince them that there is enough of a market for mopar heads to offset the cost associated with producing them, much less something exotic that won't appeal to the masses. (exotic meaning "buy alot of other unique parts to facilitate their use") They have all the pieces in place already.....so I am sure your costs will be higher.

Not trying to discourage you, just voicing my perspective.

Good Luck
