i have 2 Victor intakes. 1 Victor 340 and 1 Victor W2. i have never measured the ports. a few years back i bought a Super Victor from Hughes Engines with there stage 2 porting work. i paid a lot extra for the stage 2 porting and i had another buddy buy a Super Victor from summit racing with no port work and we measured the difference. there was none. Hughes Engines made a lot of money on me that time.
