Fuel Injectors - Which one for upgrade?

I thought I read that the stock fuel injector was 248cc/21lb for a '93 HO 4.0 motor (HO is key).

Looking for the correct 4-hole Bosch part number? Or color injector?

'97 Cherokee, 99+ intake, 62mm TB, 703 injectors (new), k&n intake, Hypertech III, 180* stat (1/8" drilled hole), 2.5" manifold 2 tail pipe (Hooker Maxflow & hi flow cat), Perf header, 4.5" zone lift, 32" GY Dura Trac, Rear head rests. Comp cam "231" & Perf head (LS1 BIG valves 2.02/1.62). 3 row alum radiator.
