After Annual ...

Finally picking up my airplane tomorrow after a 2-month annual. Just
bought it in April. It is a '61, and despite logbook entries that SAY
annuals have been done every year, it was pretty clear the majority of
stuff under the cowl hadn't been touched in a LONG time. Picking it up
tomorrow. Along with the usual, thorough preflight routine, I plan to do
one or two landings at that airport, come back, shut down and have
another look at everything before leaving to bring the airplane to my
home airport.

Have a few hundred more hours to go before a major engine overhaul, but
just about every part was taken out, scrutinized, cleaned, overhauled,
and replaced. Any tips/advice on that first test flight after that kind
of maintenance, other than the obvious?
