Milodon brass freeze plugs will not rot out, like lower cost steel ones. Your new engine assembly deserves the best. Don’t get stuck trying to replace a leaking steel freeze plug behind a motor mount a year or two from now. Milodon kits include all the necessary external block freeze plugs, cam and oil galley plugs for one complete engine.
