I've got a set of new ported Brodix B1-BA's with new Jesel shafts that I'll make you a killer deal on. Don't know why they had so many variants in this head as far as flow, but this set is 314 cfm @ .600 with awesome low lift numbers. Koffel's did the port , flow, and valve work. They designed them and seem to know how to make them work.
now you just made me slobber all over my keyboard.lol
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
