That's the problem with flat heads.
Few (no?) machine shops will travel to ones farm to grind seats with a portable seat grinder these days. This means that one must beg borrow or steal a portable seat grinder (done this in years past) or remove the block to take it to a machine shop.
Une can lap valves by hand but one cannot restore seats by lapping.
