Figured it out!!!
I've seen other people asking if it's possible and we got it working.
So many people have tried using the "--http-port 8330" at the end of the setting code but would only get rejects.
Simply change "http" to "stratum" so "--stratum-port 8330" point your antminers at the Pi's IP address with port 8330 and use a different worker name for each S1 and that's it. worker/pw doesn't matter what you use just have a different worker name for each.
Hope this helps out someone.
