7" vs. 9" vacuum booster for brakes...which is better?

67-c10...we are adding power brakes. Apparently the conversion can be either 7" or 9". Do any of you have experience with which is best? 7" presumably leaves more engine access room, but we have a straight 6 292. Does 9" give much more "boost"? Thanks in advance!
