Having all the bijuu chakra made Naruto trigger Six Paths Senjutsu. Just like having Hashirama's cells (and him being an Indra reicarnation) made Sasuke trigger his rinnegan. Now nobody knows what Hagoromo did exactly, but his chakra probably speed up the awakening process for the boys, and also gave them special abilities namely Six Paths Sage Mode and Sasuke's special tomoes in his rinnegan, which let him keep his sharingan abilities in it.

Naruto still has Six Paths Sage Mode, still has the bijuu chakra, still has the healing ability. The only difference between Hokage Naruto and teen Naruto is that Hokage Naruto doesn't have the TSB anymore because they were all destroyed but in exchange he has the other half of Kurama.
