There is an elliptical hole of 300X400 on the cover; should 300 or 400 be used in the reinforcement calculations?

The calculated diameter for openings in convex end caps is similar to that of spherical shells. Due to the symmetry of the spherical shell structure, the shell experiences the same membrane stress at any cross-section; therefore, for non-circular openings, the long axis of the opening is used as the calculated diameter, 400

Are you referring to the situation where the opening is not at the center of the head when calculating the intensity? It should be based on the major axis length
