Damn, was going to start making these to sell but for $90 its not worth it.
Jeff(Snedge) sent me a Cummins #3929792 for thr Cummins #3284170 plate. I think that's the standard gasket for the stock filter head too.
the gasket I have has a 3942915 on it which I think is the filter head gasket. it has one hole that almost exposes 2 chambers. It is half way on a separator.
