I have a Sniper intake manifold for my Gen III Hemi, part number 837032. I need to know what size (dimensions, not flow) injectors it's designed around. I got a set of Injector Dynamics ID1050x for a 6.1L Hemi, and the lower o-rings are almost impossible to get in without tearing them, and the brackets for the fuel rails are at the wrong height.

This particular manifold is designed around the LS throttle body, does that mean it's designed around LS injectors too?
