With the injectors(blow engine off with air compressor first) take the lines off each injector and take the nuts off that hold the inj to the head. I have used vise grips to grip the flat sides that DO NOT have return line holes and twist, wiggle, and pull them out. I'm not sure what the correct size is but a lug nut can be used to thread onto the top of the inj to pry on. The twisting works good to break them free before pulling or prying them out. Get an install kit with all new washers and o-rings.
I would add a governor spring kit. Remove the air horn from the manifold. Remove the fuel shutoff solenoid assembly. Clip the wire that goes over a plug that threads into the governor assemble towards the rear of the pump and unscrew the plug(some oil will drain out). Rotate the engine using the nut on the alternator pulley till you see a spring with a keeper(looks like a valve spring). There is a threaded stud in the center and 2 slots on either side(like a flat tip screw with a hole in the center). Use 2 smaller flat screw drivers or take a large one and grind/file the center out to clear the stud, and push and turn to remove the nut. The spring kit will tell ya what pieces to reuse and what to store away. There are technical ways to set the tension on these springs, but I have had good results by tightening the nut till the first time it "clicks" then 2 more clicks. Now turn the engine while watching for the other spring to come into view(there are 2 spring sets 180 degrees apart) and repeat the same steps that apply. Keep the number of clicks the same for both spring sets. The springs can be tightened further though the idle will rise and have to be lowered. I left my idle high(trying to get the rpms I wanted from my former trucks 160 pump with a mysterious history), but set my dads down(he has stock springs, just tightened them some to give him a little extra)-only down side is he has to press the gas to start the truck every time.
Well my fingers are sore and my son is hungary. Maybe someone can post some pics to show where the plug is to access the gov springs.

Any thoughts?
Any great sources for how to info? Is the above mentioned hard, as in I have gotten myself in deep doo-doo, or am I too worried?
