Queston on AE's

I know the AE code injectors are considered a "long lead" set and were an attempt by Ford to cure the "cackle" issue in the number 8 cylinder. My question is this, with a Reg. Return to be installed shortly, and DIY Stage II Injectors next... is there any reason to change the long lead tip out for a shorter one? Will it affect performance one way or another?

When your injectors are built, it will take care of the "long lead". The difference is in the pilot shot, as determined by the plunger/barrel "spill port" alignment.

"lead" means pilot shot, or "lead" injection. If I had to make a guess, I'd say the "LL" injector probably has a greater distance from the face of the plunger, to the spill port groove.

That is correct, longer pilot injection.
