Headlights: low & high beam

[Fan2zee]

Just picked up an 87' R10. It appears my top & bottom head lights are updated to use 9007 H5 bulbs. In which both top & bottom have these bulbs installed. And I have square running lights in the grille.

Question:

High beam, all lights should be on? If so, which lights should be brighter top, bottom, neither?

Low Beam, Top lights should be on?

Should I be running different bulbs in the low beam vs high beam?

Thanks
