Atlas began revamping in late 1958 with the arrival of artist Jack Kirby, a comics legend whose career was also in need of revamping, and who threw himself into the anthological science fiction, supernatural mystery, and giant-monster stories of what would become known as "pre-superhero Marvel." Heck returned alongside other soon-to-be-famous names of Marvel Comics' 1960s emergence as a pop culture phenomenon, making his first splash with the cover of "Tales of Suspense" #1 (Jan. 1959), one of the very few Atlas/Marvel covers of that time not drawn by Kirby. In the years immediately preceding the arrival of the Fantastic Four, Spider-Man, and the other popular heroes of Marvel's ascendancy, Heck gave atmospheric rendering to numerous science fiction / fantasy stories in that comic as well as in sister publications "Strange Tales", "Tales to Astonish", "Strange Worlds", "World of Fantasy", and "Journey into Mystery". Heck also contributed to such Atlas/Marvel romance comics as "Love Romances" and "My Own Romance".
