Yea.. my experience is mostly with motorcycles. When I worked for Superbike Mike, we used old valves ground down to the optimized first port's diameter to slide into the throat as a template to match up the others.
I was interested in those little bumps on the exit side of the runners... wonder if they were intentional?
