I really don't know of anyone who makes it a habit to check the torque
on all the engine bolts at each annual. Things like exhaust studs
hardware and intake bolts are checked.

The case bolts on my previous Continental IO-520, circa 1987, had white
paint stripes painted on them to indicate whether they had come loose. The
previous owner, a one-time automotive racer, had a colorful name for these
stripes but at the moment I cannot recall it.

You can use a product called "Torque Seal", available from Spruce for
this. All of your fuel connections should be done. Doesn't actually
seal the torque, but shows you if something has moved.
