New valve seals would have nothing to do with raising compression. It would
only prevent oil from getting past the valve stems.
Gary, try doing a "wet" compression check on the low pressure cylinders. If
the pressure comes up a bunch, then you are looking at rings. If the
comprssion comes up only 5 or so psi, you are looking at bad valves due to a
poor head rebuild. Just replace the heads in that case.
You may also have a bad head gasket causing the compression to be down if
they are adjacent cylinders.
