Is the revell kit that you're speeking of the CH-53G? You may be able to use some of the parts, but probably not all, because the H-53A's,B's,C's, D's, G's, and J's have about the same cabin dimensions. However, the CH-53E has a longer cabin. There will be some trimming and fitting involved. Cabin Pics of the CH-53E are available here.

Look under the heading of CH-53E reference.
