Hi
The last place i worked had a cylinder head recacing machine
We used to fly cut alloy heads to a good finish
Cast iron heads were surface ground once they were flat we used to trim the stone (segmented type) then finish off without the power feed to achive a cross hatch type of finish.
The worst heads were the alloy diesel ones with hardend steel swerl chambers pressed in
We had to grind these it used to hammer the stones
