Remove all head studs, and run an 8-inch whet stome over it with
light oil. If you can manage to stone it flat by hand it should be
okay. Do NOT take sand paper to it in a local spot, as it may end up
with a divot that could make the next head gasket leak.

200 grit? Are you sure you didn't drop a zero? If you leave sanding
scratches in the cylinder wall it will burn oil like crazy,

Pistons are available for +.060 overbore (cheaper than sleeving).
