CJ7 4.6L build KB944's

[LetchcoreCJ7]

So you may have seen my random questions posted up since I started this build. Without this site I wouldent have even bothered trying to figure all this out. My 4.6L is going in a 1983 CJ7 with 33in tires that will mostly be for light towing, mild offroading and ground pounding I will post up my specs and pictures I have taken and also some more questions I have along the way.

I have a Hesco wiring harness that includes the VSS for my D300 which should make the wiring part of this much easier

Here are my questions for now...

1. What fuel system changed will I have to do besides the E2000 pump and filter? Injector Size? Map? Fuel Regulator? I dont want to overwhelm myself with more then I need for now until I get it running and driving.

2. What headers work with the 4.0l block and CJ7 engine mounts? I have a Pacesetter and it hits the engine mounts.

So I used a socket as a spacer, longer bolt and some washers to get the harmonic balancer on the longer 258 crankshaft. So my only question now is do I still need to buy the spacer so the original bolt will hold down on the harmonic balancer or is the press fit enough to hold it in place???

I'd use the original bolt and a 1cm spacer(whether it's multiple hardened washers, hesco's $35 spacer, or a 1cm spacer machined from an old 258 hb) just to play it safe. . .
I dig the NSG-370--I wonder if there's a 2wd version(like how my 2wd ax15 has a longer output shaft and tail section).
edit: did some research and there is a 2wd version--now to compare dimensions to 2wd ax15. . .
