Would this be safe to do ?

The proof of the pudding would be in the eating.
It seems a long time for the finished result but it may just work.
One can achieve the same result in a few minutes with a figure 8 motion on a 400 grit paper.

In my opinion,rubbing compound only polishes the surface and not true it. The drill is a bad idea because it could make the surface uneven do to rocking of the head.
I tryed this on a spare head i had laying around last night but i used my hand and it really did wear some metal off but ill tell ya it took loads of time and then i set it on my cylinder without the head gasket to see if it was uneven but it was perfect, ill upload some pics later

Good that you tried it.
Could you test it with a straightedge, engineers blue or even or the old oil on glass method, to see if it is really true.
A thin smear of high viscosity oil on the surface, place on glass and observe the underside. Low spots, the oil will not touch the glass.
Tried the method you were on about and all around the head surface touched the glass not one bit didn't so im pretty sure this could work
Not the most sophisticated test in the world but it works for me as long as you do not move the head around.
I am not really in favour of a polished surface on a head, the imperfections that a tool leaves gives the copper gasket something to bed into making it leak proof.

Maybe try finding a thick piece of glass/granite counter top (perfectly smooth) And lay a 1500-2000 grit wet sandpaper and slowly move it back and forth/in circles to make it flat.
i just lay the glass on top and didn't move it at all, all the oil touched the glass, i put a nice thin layer on the head surface, yeah i got a nice flat piece of wood and glued sandpaper on to it then just kept doing full circled by hand for ages. im gonna put the head on the quad tomorrow then test to see if there's any leaks.
Just remember to leak test again after the first ride, sometimes the head/gasket will leak after being ridden because of expansion and contraction from extreme temperature changes ( hot to cold ) !
