For a guy who does as much of this work as you Mike, this machine must be just what the doctor ordered.
When I think of the requests for varying stages of porting work for all the different engines out there, how & when do you use it? Probably to make the ports equal on a given head. I can only imagine the work/testing involved determining the best shape, adding or removing material.
It would make sense to specialize, those on here think you already do, but I've seen more than just SOHC4 heads in your shop. I have both a 500 and a 750 head with broken fins that are basically scrap if they can help with further development. Not that this stuff is anything new for you.
Good luck with it Mike.
