Edelbrock/Musi heads (WOW)

BUYERS create DEMAND. Manufacturers create SUPPLY.

SUPPLY and DEMAND. That's how it works.
To a point I understand what you're saying, but the manufacturer's know that there would be a demand for their products if they would produce them. The small block Fords have 2 different cylinder heads for the milder build engine's, one is the afr's 165 and edelbrock's 170. They took a chance and offered these cylinder heads and they are selling, the aftermarket has to know that the mopar crowd would buy their cylinder heads if they were available. I would.
