Wouldn't all 351c filters have a bypass and most also an anti drain back valve?
The anti drain back and overflow valves are completely unrelated.
If the filter gets clogged, the pressure relief valve in the pump will not help lubricating the engine. The bypass valve in the filter needs to open to allow unfiltered oil to the engine or it will be toast in seconds.
Personally I run filters without a bypass valve, but they are not common and I replace it frequently. It is for some Nissan diesel truck that has the bypass in the block.
