I don't understand the problems. It's just dumb iron & aluminum. MOPAR, GM & Ford don't make those parts. Outside vendors do. They just assemble parts to build cars. The race versions of those factory Pro Stock race engines are are more similar to the other two brands than many realize. Costs money to run those cars. Teams have to what they have to do.
Been a few years, but a friend of mine was running very well in Pro Stock, the cylinder head guy he was working with told me he used the same CNC program for the ports in the GM & Dodge Pro Stock heads. They ain't all that different.
