I believe it depends on your model car (Fordor vs. Pickup/coupe), what shape the motor is in, and what grades you are going to pull. For occasional hills it I've heard it will be OK with Stock, but in foot hills, mountains, steeper grades, and longer grades you may be needing a high compression head, especially if you do not have a Mitchell.
Hopefully others can chime in who live in hilly/mountainous areas that have 1st hand experience.
