The top edge of the head between the valve cover and intake manifold needs paint too. A tip: sometimes it's easier to brush paint some areas instead of masking for spraying. Spray some paint into a paper funnel and catch it in a jar. Let it thicken for a while, un-covered. Get about a 3/4" soft brush and go at it. (Actually, don't cover the paint tightly for several days, as the container can leak or break due to the propellant pressure still in the paint).
