This is a valid point.  We make a habit out of replacing the rod bearings
whenever we replace the head gaskets, as it is only  a little bit more work to
do so.  So we take the cylinders off.

By the way, what is everyone using to remove wristpins?  Pop made a homemade
tool for this purpose that works fairly well, but I was wondering if there are
any manufactured tools for this.

That is the easy way, but the idea is not to remove the pistons when
doing a head replacement.  This works great as long as the cylinders
don't stick in the heads and come off with them.  Then you are faced
with the task of getting them over the rings, or removing the pistons.
With the piston pins usually very firmly bonded to the pistons, this can
be even more difficult than fiddling with the rings!
