Put the brisket fat side down under the pork. Put the pork above it, fat side up. Use a temp probe in each. Start checking the brisket around 185*. Leave the pork in until it gets at least 195*. I like 205*.
I would do them seperately.
I like to cook my choice grade beef set on 200*. I like to cook my shoulders and butts set on 250*.
