First try at head porting

You need the right tools for the job or it’s going to just be a buff n shine. When I think back 40 years ago to some of the stuff I did and called it head porting I gotta laugh. It took me a couple of years even after I got a flowbench to understand real head porting and what to do and what NOT to do. I have a foot speed control on my grinder and can slow down or speed up with ease.
