All I ever saw was basically the fact that FEAF considered it a "Bozo No-No" but no major action was taken. This is as opposed to later in the war when the F-86 pilots were deliberately going into China looking for MiGs landing at their airfields and trying to nail them there. Several were shot down on these raids (of which the USAF was conspicuously silent) and at least one -- Dolph Overton -- was threatened with a court martial for violating standing orders. I am not sure why but for some reason he was selected as the "goat" for what was apparently a common practice.
The only other events in which US forces and Soviets came into direct head on head clashes were the A-20G shootdown in September 1950 and the November 1952 fight between F9Fs and MiGs from the 83rd Fighter Aviation Corps in which two MiGs were shot down and one damaged.
