Can’t turn upside down? Then 51,181
Nothing says that the numbers have to be the same size, so 1008.
Maybe that’s why my photographs sometimes don’t turn out so well.
Moving only two matches I come up with 980
From the middle 0 rotate the lower left match 90 degrees to make a 9
From the right side 8 remove the lower left match, to make it 9, and add it to the upper right of the 5 to make that a 9
999
Just moving 2 matches > 980
