As you obviously realize, without the shield, well, it's just not going to be "correct"; but of coarse once installed who would know?
The actual purpose of this shield is to reduce the sum of splashed oil that might come in contact with the exhaust heat cross-over passage section of the casting located on the bottom; this intended to reduce the sum of that oil which might be "damaged" by the excessive heat exposure and even worse will tend to "coke", even becoming a solid contaminant suspended in the oil.
So, if ones' vehicle is just driven off trailer to the display parking spot, or just never allowed to get hot (for fear of burning the engine or manifold paint ), or even just never run hard producing elevated exhaust temperatures, or best, the intake manifolds' cross-over passage is blocked (reduces the burnt paint on the top of the intake issue, or is done to reduce the tendency for fueling vapor-lock ) it probably really isn't a necessary component (that is as long as you don't tell anyone its' missing! ).
