tis just my opinion, but i would get it extrude honed
no matter how steady of a hand an individual has, even if you flow bench each runner to the same cfm, there will be imperfections from it being hand done, which could lead to slightly different air fuel mixtures in each cylinder. where as, if you extrude hone it, all runners will flow exactly the same cfm, and have the same air flow pattern in them, consistantly making the same air fuel mix.
