In a perfect world, I would order a dozen of every style and measure them.  At $1.70 each (plus shipping), I was hoping to not have to re-invent the wheel.  As it is, I will be ordering about 32 of what ever I decide.  2 for each COP and 2 for each injector (X) 8 cylinders.  Obviously, doing this for 4 or 5 mixes would be very expensive.  So I was seeking guidance as to what mix to order and try.
