Most likely nothing to worry about, as long as it continues to run cool.
But it wouldn't hurt to backflush the radiator, in case any pieces got
caught in a tube.
The problem is the blue form-a-gasket (aka silicone RTV). If you aren't
very careful how you use it, it can squeeze out of the joint inside the
passages and form a bead of material that can later break off into long
strings. This is exactly the reason I don't use the stuff unless I have
access to remove the strings.
On my "LBC support vehicle", a professional mechanic used RTV when replacing
the water pump. The resulting strings clogged the heater until it wouldn't
produce any heat. Had to have it power-flushed several times, and it still
doesn't work as well as it should.
