My truck consistently ran about 5 hundredths slower than without
the spacer. To confirm this, I then removed the spacer, and got my 5
hundredths back. This was all done on the same day. Also, with the spacer
on, my upper intake appeared to be just as hot as it was without it, certainly
too hot to touch without getting burned.

I know I put the spacer on a few weeks ago, and took it for a ride. I drove the truck hard, and I could tell that when I popped the hood and the motor was hot, the blower was hot, and the intake plenum was not even warm. It was more cool than anything. It was a cold night, but I think the spacer blocks some of the heat coming from the motor/blower from getting back into the intake...
I may be wrong and I dont mean to get involved here when I shouldn't but I don't think you can blame the spacer for a loss of et times... If anything it's helping you and something else is the problem. Just my $0.02

Can the EGR opening immediately before the upper plenum just be blocked off with a plate? ...meaning, I wedge a piece of metal between the EGR and plenum, and bolt it back up to keep the exhaust gases from entering...
Would that be an option? Then it still looks stock

My egt gauge says that at cruising the temps an inch from the header flange is around 1300°. I'm guessing by the time that gas travels down the header then up to the egr temps may be around 500°+. 500°+ temps going into the supercharger and through the intercooler only serve to heat up the temps.

My understanding is that it closes at idle as well.

...so what you're wsaying is that if we just drive around all the time at WOT, our intakes would be cooler. I like that idea.
Problem solved in my book.
