Hello Donald
You might want to check if the valve cover is seating all the way down. There is a flange spot welded on the inside of the valve cover along the intake side, if I remember, sometimes that flange will not clear the cast lip on the head and it will feel like the cover is seated. But its not. Hope that helps.
