I would say bench bleed it well, cap the ports, install and bleed as usual. the other thing you could do is install a different booster or a bracket that places the booster/master cyl level or slightly downward.
if you have a few coils of brake line coming off the master ensure they are all placed in a fashion and the lines run so any trapped air will find it's way to the top and out into the master cyl reservoir so, no low spots or line that is crossed over and no line that comes above the fitting that goes into the master cyl.
personally I like the coils there or flexible line because it allows the master cyl to be moved around some, like unbolting it for manual operation with a rod or screwdriver which enables you to bleed the system on vehicles with the tipped master cyl angle or for checking the pushrod clearance on vehicles with brake bleeding or other issues.
