Fuel Rails?
I have a 351w 5.8L 1993 F-150. I was wondering if replacing my factory fuel rails with aftermarket performance rails is a good idea, and if so, should i use low or high impedance injectors?

What else are you doing to the engine? New fuel rails and new injectors are going to give you absolutely nothing, because the fuel requirement for the engine is exactly the same as it was before. Stick with stock stuff if everything else is stock. I think stock injectors are high impedance - around 14-15 ohms - if you use the others, you will burn up the computer.

i have already purchased a set of shorty headers, and i'm fixing to bolt them on while running true dual exhaust with 2 40Series Flowmaster mufflers; i've put a set of accel wires and distributor cap on the engine also. i've thought about changing out the heads but i'm not sure yet. i want to add performance to the truck, but it is a daily driver, therefore not too much money to spend on it.

The stock injectors and fuel rails will be perfectly fine for the mods you are wanting to do. Spend your money on something other than injectors and fuel rails - they won't gain you a thing on their own.
