This is a photo of the drivers side of the engine. See those two holes underneath the oil pressure sensor? Does an oil filter get plumbed into them? | | |

The filter would get its supply from a T fitting from the oil pressure port, and return in a hole further up on the block.

If you clean them out, there will be threads in a blind-bottomed hole, no connection to any oil passages.

Just above the bottom lip of the engine is an oil gallery that runs from front to back. This is the pressure side. A couple inches above it is the return gallery...same front to back. That's where your sensor is located.
Above the return gallery, towards the back of the engine is the threaded throttle bell-crank mount where your gas pedal forward motion is changed to up and down motion to work your carb linkage.
Eliminating the bypass filter will pick up 5-7 more pounds of oil pressure. Hope this helps.
