Does anyone have any port sizes in inches for box stock heads like a original B1 head? Also any other big block heads that are considered big. I'd even like to hear some small block w2 #'s or any small block head. Thanks

How about any possible big block or small block head?

Take a look at the OOTB results on the Victor M.W. heads and also look at my Post about different M.W. Size opening. I have a ported set of B1 also but thier not stock anymore If your interested in flow numbers my ported B1 flowed 420 CFM at .700,.800 and .900. My CNC ported 440-1 flowed 370 @.600 and .700, ported B1-BS to M.W. size flow 350 @.0600 and .700, my SR M.W. flowed 340 @ .600 and .700
