Hi Guys;
  I am busy just trying to keep the business running...
    Customers want me to port and polish.
  Well, I am not an airflow dynamics Engineer, I don't own a Dyno... and no interest in either. 
  As I am a all-out CNC shop... I wonder...
     Is there a source for proven CAD models for various cylinder heads that I can just punch into my software and create tool-pathing?
  Thanks,
  Mark
