The lines used with the 1/8" connections will be mighty small inside and will limit the flow some what.
But Jerry is right, if you are using an aftermarket filter set up you'll want either a restricted filter, or the 1/16" restrictor in the line.
The Wix oil filter with the restrictor in it is 51050. Napa number is 1050. You FLAPS should be able to exchange these numbers if they don't handle Wix or Napa filters.
After reading your post again, it sounds like the filter is plumbed into to the pressure side on both the drivers side of the engine and the passenger side. Coming off the oil pressure fitting, to the filter, then to the passenger side port on the head means both lines are tied into a pressure port. So not sure how much filtering will happen.
