How come W2 heads aren't made by all

Batten and Indy are the only one's t copy-ish the W2 head. When Edelbrock came out with there head, the price was right and the flow rates just behind the W2 at half the price. Wht go W2 at this point?

the biggest problem with MoPar is;

Pricing
Letting the people know they have a good deal (?) somewhere at some time.
Advertisement issue's.
Added expense over a stock head. Rocker arms and now, the W2 needs rocker stands.
At one point, they must have had 10 different versions of the head out which makes it confusing for a local Joe to up the anti on his car to compete with the other brands.

IF MoPar advertised and divided the heads up into catogories, like one for the street guys, like they recently did but years ago would have been nicer, and cut the expense down on a good head, you would have seen more W2 engines roaming the street killing the Fords and Chevy guys.

MoPar can only blame themselfs for there failure.
