-Ootb w2’s....... every set I’ve seen had noticeably different port bias between left and right intake ports.
Ootb, #1 has always flowed more than #3 for me.
So, whether it flows 260 or 240 can easily just be the difference of which port was tested.
Each port flow a little differently. No matter the head, ported or not. It would be nice if it was easy enough for the man to do to make it cheap enough to do all 8 ports.
