Well I will say that looks interesting, but I'm still skeptical. I dont think it would add huge flow but I would agree it probably helps vaporization.
I do a modification with a 1/8th inch drill bit that looks the same as that surface, but I do it to increase surface area to improove cooling in air cooled engines all thruout the cooling fins and jug.
it would be real easy for one of us to replicate with a drill bit then dyno. I'm willing to do it but I dont have time for at least three weeks.
Just for fun I'll tell my racing partners that I'm doing this to reduce valve weight and see what they say.
