I think Extrude Hone has the advantage of less port to port, runner to runner flow variablity..by nature it will port the tighter area more and more open areas less. But the cost of removing lots of material with E. Hone and the inability to alter shape are in favoer of hand porting. Therefore, I suspect the BEST solution would be hand porting to basic shape & size FOLLOWED by 1-2 Extrude Hone passes to equalize flow, fine "flow tune" the shape and put a nice finish on things..SCC and other tuner mag writeups have talked about this favorably.
