(Coolant) Installing freeze/expansion plugs in the coolant ports to the intake.
Since this seems to be coming up a lot lately I took some pictures of how I do it. Out of 10+ motors I have only had one leak (previous owner installed plugs and pried them out leaving some pretty nasty grooves).
Get yourself some 20mm freeze (expansion) plugs, I use napa because they seem to always have them in stock. part #381-2151 They should run you about $2.
Clean the ports in the housings well, and check for burrs, or irregularities. A fine grit sandpaper and your finger will smooth out any imperfections quite nicely.
Acquire a suitable installation driver tool, I use a craftsman 6in 3/8 drive socket extension.
A light coat of rtv will act as a lubricant for install and as a sealing agent once they are in.
With a hammer and your socket extension (or other appropriately sized tool) drive them in square to the housing, and just below the surface.
Clean up the errant rtv, and put it all back together. I usually let them cure for a few hours before re-assembly, and overnight before running.

Yeah, that's what I was thinking too. The coolant passages going into the intake manifold are only there to heat it up faster in the winter, right? How much of an effect does blocking them off have on cold weather starts, even if I keep my choke?

I have a block-off plate for the ACV, and since I'd be installing a new intake gasket anyway, I'd be making absolutely sure that I'm getting the right one. Unless I'm missing something obvious...?
