Heinkel Rostock produced as many He 111 as Junkers assembled Ju 88 in Bernburg, only the license production of the Ju 88 made the difference (facs switched from He 111). Heinkel Oranienburg made Ju 88, not the main factory in Rostock.
With some rare exception Heinkel delivered 100+ He 111 per month from July 41 to July 44
1939: 1400 He 111 vs 110 Ju 88
1940: 827 He 111 vs 2184 Ju 88
1941: 930 He 111 vs 2619 Ju 88
->Ju 88 production is all variants, several hundred recons built in 40/41
