You are correct in that the test isnt 100%, but then again nothing really is. LOL I understand the kit is pricey, call around to see what a shop would charge to do it, sometimes it is less than the kit.A 4 or 5 gas analyzer will do the same thing, and a little more accuratly, but most places wont use their emissions equipment for doing that.I have seen many head gaskets do exactly what you describe. Since you have replaced evey part of the cooling system, it honestly looks like the head gasket is the direction you are headed in. Toyotas dont tend to crack heads either, not to say it isnt possible, but I cant recall seeing it
