The tuners are very tight on those 2+2 Gibson style headstocks.
The tuners should be orientated so the tuning post and gear wheel is nearer the nut than the tuner button and its worm gear. This lets the string tension pull the gear wheel onto the worm gear for minimum play in the gears. Having the tuner orientation reversed allows the string tension to pull the gears apart, which isn’t a good thing.
If the space between the tuners allows, I’d angle the tuners so that the tuning button posts are at right-angles to the long axis of the neck. If you look at pictures of Gibson EB-0 and EB-3 basses, that’s how they are arranged.
