93 4.0L H.O. Injector swap question

My '93 4.0L HO is running LEAN.
NO vacuum leaks, no exhaust leaks.

I have the Pacesetter header, and K&N CAI

Stock injectors.

I want to swap in injectors to fatten it up, Injectors with more flow, so my question is:

What injectors will flow more fuel, and bolt into my YJ?

Think Pick&Pull, so year make model & engine...

Those injectors are easy to hide in the bottom of your toolbox, so I might grab a couple extra, you know, to save me the trip if I get a bad one....

The 2 best mated to a 4.0L for a swap are the Ford 86 and newer 5.0L yellow top injectors, or...A bosch 703 found in the 90's Dodge neon 4cyl. Black top.

Both are a plug and play injector on the 4.0L and both have a 4 hole nozzle for the better atomization pattern in the spray.
