I'm assuming that the valves and springs are in place and the valves are
all closed. If so, no problem with the working bits, the seats should
still be clean.
Drop by your local Ace hardware store and pick up an eight inch
rectangular wet stone, the thing usually used for knife sharpening. One
side will be coarse grained, the other side will be fine grained. Squirt
a glob of your favorite engine oil on the coarse side and proceed to give
the flat surface of the head a good rub down. In about a minute it will
be clean and shiny again, still perfectly flat with almost no material
removed. Do remember to wash the head well to remove the grit before
The wet stone is a cheap tool, good for a lifetime of this sort of thing.
I keep one in reserve just for these flat surfaces and nothing else, so
it stays flat.
