Nice post Red Sleeper.
I agree with your parts suggestions on a reasonably stout VE.
As far as the fuel pin - the Denny profile is far too smoky for a somewhat tweaked street driven VE.
I'd suggest a pin from the THD or BD or this one here - both linear profiles -
New VE Fuel Pin for 89-93 Dodge VE Inj Pumps
79powerwagon above made a couple nice looking pins as well, may want to PM him.
If you tweak the VE enough and/or have substantially larger injectors, stick with your stock pin & play with the infinitely adjustable ramp profiles it has.
Valve spring wise - the same listed $150 + #60 marine springs can be had for $100 here -
C14010 or 3916691 1989-98 Cummins HD Valve Springs
That site has the rest of the parts listed like gov spring, lift pump kit, etc, for a bit cheaper, but shop around.
As far as the lift pump - you're better off having a high volume piston setup rather than the stock diaphragm pump. Better cooling, more consistent timing advance, no deezul in the sump if something goes wrong, etc etc. If you're planning to run over 20psi consistently, stake or retainer ring + set screw your VE front seal.
If you're on a tight budget, retorque your factory head bolts using a cold 3 step process, and clean up the area under the valve seats if you are so inclined to pull the head.
Get a better converter with a somewhat tighter, more efficient fluid coupling, up your line pressure & tweak the governor pressure & TV cable to get near your desired shift RPM. If you up your line pressure, get the billet servo, accumulator, band strut & band anchor package.
Adjust your bands to a 1/4" gap or by rotating the driveshaft till barely unbinding, & ignore the factory suggested torque settings.
