Any Merc dealer. The same one is used for all carbed Merc BBC engines. Make sure to use the factory gasket with NO sealer or your temp gauges will not work.

I ran NGK UR5's( NGK stock #2771) in my 525SC stock and after bumping it up a little. They are the same heat range as the stock AC R41T's, but have a slightly extended tip to help the engine idle better and keep them fouling.
