You can cap them and the manifold barbs off. The EGR might still be hotter than the coolant any that point, but it was not a problem on the ‘91 I fixed up. The main thing is to not use vacuum caps on the manifold barbs. The are not reinforced and soon leak under pressure and cut under a clamp.
If you have the nipples on the spacer and the manifold, EFI hose the right size to run the coolant is plenty heavy and is a longer term solution than trying to cap them off.
Or plug in the back of the intake and JB weld and hammer and dolly to flatten the barb on the heater tube.
I though the coolant through the egr plate was to 'cool' the recirculating exhaust gases.
Meh, what do I know

The plate can de ice and cool on the same days in some states.

The egr spacer has been tapped and plugs installed by p.o. (See pic) I'd like to run a hose from front to back so if I choose later took hook it back up everything is still good.I'm not worried about Ice here, and doesn't the egr just put exhaust back in intake till engine is warmed up?

No, that’s not what EGR is for. It lowers the combustion temp to reduce the formation of certain emissions, like NOx.

How Exhaust Gas Recirculation (EGR) system works
What is an Exhaust Gas Recirculation (EGR) system in a car and how it work works. How the EGR system flow is monitored
Read post #8 from jrichker here. The thread should be about EGR and the AIR system as both are for smog control, and post #8 clears it up.

Exhaust - EGR and SMOG Systems - KOEO code 34
Hello again! Okay moving onto the next KOEO code - 34 for the 87 5.0. This code is interesting because it does seem like the car runs a little smelly and I would like to make it run better and cleaner if possible. So the previous owner(s) removed all EGR and smog components. Currently installed...

Mac throttle bodies also had a whistle to them, my buddy had one on his 92 LX and it was noticeable for sure.
I've noticed that my stock tb has a hole in the blade and so does the explorer gt40 tb. Neither of them whistle so maybe drilling the same size hole in the same location is what stops the noise.
I always thought that the whistle noise was air flowing through the IAC ports in the throttle body and not related to the blade.
From what I've read when I was looking into it the belief at the time was air going past the opening of the egr plate was causing the noise, the fix was to round off the sharp edges of the openings, there was mixed results IIRC.
When I get the junk pile running again I've got stuff to experiment with.

Do one thing or the other, to get accurate results only change one thing, if it don't work do the other, if both are done at the same time we won't know what the fix is.

The hole in the plate is for extra idle air without the plate being so open that the TPS bring out of range.
Rounding the IAC passage corners will not affect flow much, but should affect whistling greatly.
