As far as you stating he indiactes nothing that would point to a headgasket, I'm guessing you think antifreeze evaporates on a regular basis from a sealed system then.
as far as being "least invasive", pressure checking the cooling system is about as simple as it gets, twist off the radiator cap, screw on the pressure tester, pump it up and let it sit for a couple minutes.....sure sounds less invasive, and infact cheaper (it doesnt cost a penny to do, and most autozones or any other auto parts store will loan the tool), and if it indeed looses preasure, saves going thru the process of elimination by swaping parts that are fine to begin with, hence saving time and money.
theres also another test that detects CO2 (which would be present if theres combustion in the system), it costs about $20 at most parts stores, and is a very accurate chemical test.....the downside is that it only indicates if theres CO2 in the system, if theres any other leak besides engine combustion being forced into the cooling system, this test will not find it.

i kknow what bubble testing is and back flushing your system and pressurising it with water is an easy way to check for external leaks plus it never hurts to have a clean cooling system that is why it is the least invasive not to say that a leak down test is wrong but if you don't have the tool you can work with what you have and onceyou have clean pure water in the system it is faiorly noticable when you have oil in your cooling system.

take it or leave it
I told the man to back flush his system doing that alone can unclog a dirty heater core because you are sending fresh water through you heater core backwards hins the term back flush!!!

Did I read somewhere that you guys wouldn't change the Tstat and water pump, hoses and belt if doing a head gasket? Makes sense to me to change that stuff while you're in there and got it apart...
