Is their a way to calculate what face of a part a raycast hit?

Use the following tutorial, I found it quite helpful!

How do you find the side of a part using raycasting?

This is answering the literal title of your post. IT’S MATH TIME! Part of what is returned by a raycasting operation is a normal vector, which is a directional unit vector that faces straight out of whatever face was hit by the raycast. If you simply want to find the side of the part we hit, we can compare the normal vector we hit to the vectors that make up the face normals of the part and return the face for the given side. This leaves us a question: how would we compare two vectors to see…
