33lg VS 95vp chain question

[rjh245]

Here is the question. I guy I work with has a craftsman chain saw. One of the 55cc models. The saw came with a narrow kerf bar and a 95vp chain. My friend got another chain for the saw, but at Sears they sold him a 33 vp chain they said it was the same thing. Both the chains are 72 drive links of .325 chain for an 18 inch bar.
Here is the question. Can the 33 seires chain be used on the narrow kerf bar?
