Naruto would likely become more understanding of Itachi's past and the sacrifices he made. His view of the Uchiha clan and the concept of loyalty would be broadened. For Itachi, being with Naruto during the time travel might make him more open about his emotions. He would start to rely on Naruto not just as a comrade but also as someone he has deeper feelings for.
Naruto's character would grow in maturity. He would learn from Itachi's wisdom and experiences in different time periods. His naivete would be replaced by a more calculated approach in some situations. Itachi would also change. His cold exterior would start to thaw as he spends more time with Naruto. He would start to show more vulnerability and his love for Naruto would make him question some of his previous beliefs about his own life and purpose. This would all be a slow and gradual process as they face various challenges during their time travels.
