If it were mine, I’d replace the base gasket. Soak it in oil before installing. Deck your head on glass with 1000 grit sandpaper until mirror shiny, and reinstall it. Torque properly in criss cross pattern. Start it up. Retorque once warmed up, and again after 10 miles, 50 miles, and 100 miles. Rings should be fine, you’re barely broke in.
