the whiskers were not because of kurama kishimoto originally had Naruto as an an actual fox spirit and he had whiskers but he than changed it to where he was the host the whiskers were always part of his design

the whiskers are simply a character design nothing in the manga anime or databook states the whiskers are from kurama

another thing kurama's chakra never entered naruto when in birth

it was said that the jinchuuriki's individual chakra there own not the tailed beast is diverted to the child and thats why the seal weakens

also when a jinchuuriki absorbs the chakra of the bijuu it is transmuted so when naruto enters bijuu mode his cloak is actually his own chakra kurama simply acts like a battery that can allow him to recover chakra faster but the chakra cloak is made out of naruto's chakra which was described by karin as bright orange and warm
