Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

As long as the castings are good. Which heads were cast in Australia? The Poly guys had some 4 barrel intakes cast in Mexico here a few years back. They worked and even though they were pricy, sold like hotcakes. View attachment 1716242428

The original run of those were done by The Foundry Works IIRC, curious if that was a 2nd , or 3rd run done in Mexico.
