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

There’s cheap then there’s on a budget and I get so tired of hearing how expensive Mopars are. To many 11 second or slower spend money stupidity on things their engines don’t need. It’s only because guys are lazy or maybe afraid of Facebook. I pass up deal’s daily or pass them on to others. I just found what is supposed to be an untouched Victor340 for 250.00 that I am passing on to one of our members. I also posted that I need a set of 340 main caps for him for an engine I have. No luck on that yet but I tried because I can reach out to 1000’s of people for him.
