It doesn´t matter...yes it is simple.
The difference is in internal passsage diam., but just drop in the 5 port sleeve and it works fine, and guess what, with the 3 port crank it has more top end....you loose a bit in low end, but not that much...OS has tons of it....been there tried it both ways.
my 2 cents
