The angled decks were not added for Korea. The details of this modernization package are below from "GlobalSecurity.org"
Essex Class (SCB 27A/125): CV 9, 10, 12, 15, 18, 20, 33, 39 -- On 04 June 1947 the CNO approved Project 27A by which Essex-class carriers were modernized to be able to handle aircraft to 40,000 pounds and included the installation of two H-8 catapults, strengthening the flight deck and clearing it of guns, increasing elevator capacity and adding special provisions for jet aircraft such as blast deflectors. USS Oriskany (CV 34), the first of nine carriers modernized under this project, began conversion at the New York Naval Shipyard on 01 October 1947. Oriskany became the prototype, while Essex was the second carrier to be modernized to the SCB-27A design. The USS Essex (CV 9) was placed out of commission in reserve on 09 January 1947. The first of the World War II carriers to do so, she then underwent modernization which gave her a new flight deck, and a streamlined island superstructure. USS Essex (CV 9) was recommissioned 16 January 1951, and on 23 August 1951 she went into combat in Korea, the first carrier to launch F2H Banshee twinjet fighters on combat missions. The SCB-27 modernization was very extensive, requiring two years for each carrier. To handle much heavier, faster aircraft, flight deck structure was massively reinforced. Stronger elevators, much more powerful catapults, and new arresting gear were installed. A distinctive new feature was a new island. Ready rooms were moved to below the hangar deck, with a large escalator on the starboard side amidships to move airmen up to the flight deck. Internally, aviation gasoline storage was increased by nearly half and its pumping capacity enhanced. Also improved were electrical generating power, fire protection, and weapons stowage and handling facilities. All this added considerable weight: displacement increased by some twenty percent.
