Noticed I can pick this up second hand for a song - https://lmr.com/item/HLY-30072S/1986-1993-Mustang-50L-Holley-Systemax-Ii-Intake-Manifold-Kit

Would I notice any real performance increases in my '91 MGM?

Wouldn't help a LoPo engine very much, if anything it would aggravate the speed density system. That intake is designed for more flow at higher RPM, which isn't very useful when your engine is done at 4100 RPM.

If you can find a HO upper, I'd just grab that, bore your EGR spacer out, and do the TB mod to use a larger HO type one. That'll give a nice little bump in throttle response.

Do not become complacent with VerticalScope "working" in the background.

Tracking. Thanks, brother, exactly the info I needed to pass! Will keep an eye out on the other items, though.
