I'd tend to disagree a bit here too, once the coolant is drained the water
pump doesn't get any lubrication, least i don't think it does, my Dad was
always big one never spinning a dry pump, always has stuck with me.
I think a taste of the exhaust steam will confirm/deny if any antifreeze is
in it, just a wet dab on your finger is all that's needed....with what's left
over you can feed to nieghbors howling dog:)
A compression test will reveal if a headgasket is shot between cylinders,
as someone else mentioned pressurizing eack cylinder at TDC and looking for
bubbles in the radiator will tell you if you need to pull the head as well.
