There are any number of possible ways to approach this cheaply and quickly.
If it is just sticking from crud (technical description) it is sticking at
the stem near the head. Very unlikely it is sticking at the spring/stem
end. I would try pulling the plug and spraying (take your pick) at the base
of the valve guide of both valves when they are open from jogging the
engine over. Put the plug back in but don't connect the wire yet. Start it
and run it a few seconds then shut it off and do the spray bit again. Then
after the second running, connect the plug wire and try it.
If that doesn't work my next move would be to pull the rocker cover and
being sure that the piston was down press the valves down from the top
while spraying whatever up under the seals. You should be able to tell from
the top which valve is sticking and if one has a weak spring (or even a
broken one). If a spring is just weak try switching it out with one from a
valve that is not sticking (being sure that neither valve drops).

It might buy you some time...
For what it is worth (flame shield up) I learned a very long time ago to
not put a lot of credence in what a lot of "mechanics" "think" might be
wrong.

My Farmall Super MTA was bought at a bargain price many years ago, knowing
that it had a "soft" knock that the dealers top mechanic was just
"positive" was a damaged timing gear. I bought it planning an engine
rebuild anyway so I wasn't too concerned. Funny thing... apparently a
damaged timing gear and a piston broken in half make the same sound  :-)
It made a great tractor, still is. Has the same high quality surface of
rust and thin paint it had when I found it.
