Vmax is CNC ported by machine, Bo White is hand ported with a shaft mod, BBK is a 95mm or 102mm TB. IMO take BBK out of the equation, the opening of the manifold is 90mm or 92mm.... I forget.
So stock ported TB is the way to go unless you are buying a FAST 102 IM.
Go with Bo White. Or go Vmax and then have Bo do his shaft mod on it
