I milled mine .020
Two reasons, to get a good flat surface and to increase a little on the

If you do this make real sure it hasn't been milled before and that once you
put it back together loosen the valve clearance on the rockers or you'll
might burn or break a valve

I was considering milling the original head, but
I would rather mill a second head and keep the original
