>  As the matrix is passed to hypre it is passed as a AIJ matrix without a block size. This is because hypre has no concept of a BAIJ matrix. So yes, your PETSc part of the code is using a BAIJ matrix but hypre is doing a scalar ILU without a block size.

Thanks for the clarification.Is there much overhead in this conversion?  Would I be better off working with a AIJ matrix in the "driver code"?
