Which B1 heads did you go with on the new build. Looks great and sounds even better?



B1 Originals... ported by Jeff @ Modern..




What was the total CFM after all the port work?



The cnc program Jeff used, I think he claims something like 415 @ .700, I've had them on two other benches and they read in at 425 and 445... So my answer is somewhere over 400 cfm
