There are lots of ways of sorting out an unadjustable gap.
(Sunk valves would tend to close up gaps, which is the opposite of what you
are experiencing.)
Replacing all the rockers seems a little extreme. A new, and possibly longer
valve, might solve it. Or one new second-hand rocker. Failing that, grinding
a few thou off the bottom of the rocker posts, thereby closing up all the
gaps, might also do so.
Good luck!
