Sounds like a good idea to scan those 340 cfm ports and convert them to an NC file for CNC porting. That might bring the price down to a level where people can afford them.
Nine years ago I looked into it. That was when we had test ports in Edelbrock RPM and Stealth heads flowing in the 350 cfm range. For me the cost was prohibitive and I was unconvinced that the program would remain proprietary.
I play the Lotto once every coupla months, if I hit it, we'll spend the $280,000 to get our own 5 axis.
