Have u found that sharper runner dividers are a help , or opposite like moist porters say ? Was looking ur intake over a little ,
just curious , I know u have way more porting experiance than I do--------I sharpened mine , but tried to leave them rounded as much as possible / being thinner . ????

Everything I’ve seen or read has said to avoid sharp edges as is screws with things. I always think (airplane wing) when it comes to the dividers. After I thin them I try to go back in an round them as a last procedure.
