I’ve recently heard that you could hit desired transfer #s by grinding the piston, I’ve never heard of a full port job that way.Sanding the piston crown at the ex and uppers are a good way to to test numbers without the risk of trashing a good cylinder.
Several shops around here port saws by only grinding the piston.
Interesting concept.
