You could probably give it 5 deg MORE advance and it would be
stronger still. It's a compromise between power and longevity.
Doesn't this engine have a mechanical advance? Is it working? The
vacuum advance on most of our cars doesn't do anything most of the
time. I don't know about the Type 4 engine, but I assume it's much
the same.
Or is this your 1500S engine? If so, what is the stock timing
setting? My advance suggestion was for your Type 4 engine which you
were timing for 40 deg max mech advance. I'd like to see you try 35
and see if that helps the temp problem.

Those are plugs for the spring loaded pins that do the shift rod
detents. Early cars had a sort of brown plastic/rubber plug, while
later ones were alum. They are usually hollow on the outside end, so
you can screw a tap in them and pull them out. If they are the early
soft ones, you might find a small ball bearing or BB that you could
force down that hole to expand the OD a bit. I'm not at all sure
about what constitutes a good solution here; just thinking out loud.
They don't usually leak; there's no pressure there.
