My experience with Chinese "hard engine parts", is that machining performed in the US with US inspections and machine maintenance greatly improves the finished product. So that is good news. If I was Speedmaster, I wouldn't hide the steps you just found out, I would advertise the information. Another example of a company that can make this production method work is Molnar. Design and engineering in the US, Rough product from China, finish machining and inspection in the US. Need to get some of these heads on the track and street ASAP and really try and "prove them".
