IMO unless those are original rings, if the rings are worn, so are the
liners. Modern chrome-alloy rings are very hard, tend to wear at about
the same rate as the cylinder wall.

Yes ! Find some suitable 'furniture' (I've used 1/2" drive sockets) to
put over the 2 head studs, and clamp the liners into place. There's a
nice photo on page B21 of the factory workshop manual showing the
Churchill tool for this. Let me know if you need a scan of it.

The only ones I've ever had trouble with were on a badly rusted engine.
Usually, they come out pretty easy. But then, I normally use a hammer
and drift (made from a brass cap on a length of 3/4" water pipe) to tap
them out.

There's at least some chance you can "get away" with it. But, you sure
are going to be mad at yourself, when those fig 8 gaskets leak, and you
have to repeat the entire teardown to replace them ! If there's enough
of a ridge to need reaming, replace the liners !
