Jim, the complete engine gasket set actually includes more gaskets and
o-rings than the two separate kits and is cheaper.  This is the best
thing to get if you are replacing heads.  I would recommend taking both
heads to a machine shop for an inspection and pressure test.  If they
pass the pressure test and the machine shop sees that any cracks are
within limits (see Bentley) then you can have a valve job done.  Be sure
to have any pits on the head surface repaired (welded or jb welded) and
also repair any pits on the engine mating surface (jb weld).  That way
you will be assured of a good seal once everything is back together.

Hope this helps,
