Normal Naruto's and Sasuke's chakra reserves are close to each other, but they are also really young and are both not at their maximum level

No they aren't, Naruto is an Uzumaki and also a Jinchuriki. Even when he isn't using Kurama's chakra, due to their chakra merging so many times and due to him being Kushina's son his chakra reserves are naturally very large. When he was just a young 12 year old boy with horrible chakra control Kakashi stated he already had about 4x the amount of chakra that he had. Naruto's reserves naturally are much stronger and larger than Sasuke's are.
