Milled Head ?
How much can be milled before it's junk? And if you can mill the head a little do they make a head gasket that is a little thicker than a stock head gasket?

Not a lot iirc .008" and that's already pushing it as far as the tensioner and chain guide. You could use a slightly thicker head gasket, but you dont want to go too thick or you'll alter the quench area in the combustion chamber.

Yes, it's 0.2mm max but there are some extra rules (so it's not always 0.2mm max)
The head height plays a role too, new is between 104.95mm and 105.05mm, the 0.2mm max is based on the 105.00 head height.
IOW: never machine it thinner than 104.80mm.
I'm using my MY00 head on the MY05 engine, machined to this limit and without issues, for 110000km. and counting.

0.2mm max is based on the 105.00
So the OEM head gasket is 0.76 mm or 0.03"
Spoon head gasket is 0.46mm or 0.018
So if you have a head with 105.00mm and you use a spoon head gasket will it throw of the chain geometry?
The max you can resurface is 0.2mm, the diference between the oem and spoon headgasket is 0.3mm
Is that correct ?

acording to billman250 if you mill the head to much it will cause rapid wear on chain , chain sprocket and guide , and that clicking noise all the way.
The geometry will be screwed.
now pistons hitting the head is another league of problem hehe

A human hair is ~.003" So two hairs worth of difference to cause major issues? yeah, no.
