This is my personal observation, but having attended several Bible conferences and searched the internet on both sides, I noticed several things why KJV believers chose to believe whether or not Paul wrote Hebrews:

1. Those who believe that even the titles, headings, and postscripts in the KJV are inspired say Paul wrote Hebrews because the title says so.
2. Those who believe that Paul preached two gospels - Kingdom Gospel and Grace Gospel - say that Paul, at first, wrote Hebrews and preached the Kingdom Gospel.
3. Those who believe that the text of the KJV is inspired but the headings are not say that Paul could not have written Hebrews for dispensational reasons.
