If Speedway is good without it then you should be good.. but IMO you might blow the inner seals because you are creating pressure inside of those tubes.. & you might want to find a way to put set screws inside to retain the inner seals.. But that is what I think.. 
With all the issues that I have had with BB's rear-end.. I worked with Jason(GMR) on making my own housing the way I thought would work better.. Carrys more oil, Does not need inner axle seals but designed a way to keep the oil in the center section, & allows me a surface for my three link.. Last week Jason delivered three housings.. More to it.. but will show the end product later..

Cris are you referring to the GMR housing? Do they run inner (center section) seals?

Wish I knew the info first hand, but Randy Bell was having a problem with fluild pushing through the seals. The tube vents coupled with the center section vent fixed the problem...according to Ron's discussion with Randy. 
 
I can steal information and ideas like no one else.  LOL
