I'm looking for the font used for King's name on the cover.

Pacella Latina  Suggested by conman1985 

A lot of the iconic 1980s Stephen King book covers use Pacella Latina, a typeface designed by Vincent Pacella for Photo-Lettering, Inc. Trims have been made to the wedge-shaped serifs on some letters for aesthetic reasons or to help tighten the spacing without compromising legibility.
