(Square Top, Skunk2) > VICS > VTCS. Not sure where the old BEGI one fits in that hierarchy, but IIRC a bunch of them were made for the BP6D head so check that it fits.
Square top and S2 are about the same for power, but square top is OEM quality and S2 is... not.
Taking the butterflies out of the VTCS makes it slightly less garbage but doesn't move it out of last place. If by "full porting" you mean carving out everything inside it to turn it into one giant plenum, that seems to be a waste of time, I've never seen anyone post a dyno chart showing more power from it.

Yea I was gonna try to do that because I did see somewhere on a forum that they did it but I don't remember if there was dyno sheets or gains. Also I got a bp5a(msm bp4w) head and a vvt head. Im thinking of putting the vvt head on. Or should I put the Bp5a head on.
