Another option I have used is to weld an old ball onto a piece of steel
rod. Then use this ball with some valve lapping compound to lap the seat
in the housing. This will clean up any small dings in the seat which may
have been caused by bits and pieces flowing through at various times
(especially after a major engine failure!)

All it takes is a tiny chip or even a hair from a cleaning brush to screw
up
the relief system. Generally I found the answer to clean the seat carefully
then tap the ball onto the seat lightly then reassemble.
