Don't know for sure, but try searching the DPFI to MPI swap and see if anything head related has to be swapped over. They LOOK pretty damn close, I had to use the B7 cam in my kids B2 motor when I did the head gasket last month. I couldn't see any difference between the two.

Since I've got three B7 motor setup's and twp B2's, I will be searching the same thing.
