there are markers on the bottom face of the head near the corners, they show the machinist how much he can take off.
ive pulled a head off an ed and it had been machined past these points and was still running fine, besides the head gasket was leaking. machining that far would have bumped up the compression too

My advice i machine until it's flat and stop. either that or you will end up with timing chain noise.
