Just to be clear I am not looking for a new engine in a can. I was just asking to possibly add some longevity to my current engine. I figure it is just like my own aging body, I know there is no pill in a bottle that is going to give me my 20's back. That does not stop me from taking some vitamins and supplements. After 42 years and sitting for 5 years there is some sludge and wear to engine. I am leaning more towards cam bearings myself. This truck is my junkyard hauler, I take it every other week to junkyard. I also use it on occasion to take to the recycle center to drop off scrap metal and yard debris. Since I have had this truck it has not seen WOT but once. The truck passes CO state emissions every time and is pretty good running vehicle. If engine does bite the dust I would like to do a LS swap but CO emissions is a pain since everything needs to come from donor vehicle. So right now this truck is low on the priority list for any major improvements but we all know how quickly projects can change.
I like Project Farm on youtube, I like his comparison vids entertaining. He was the guy I watched using seafoam in his old ford truck 4 banger. I also watch visegrip garage and how he likes berrymans gas treatment. So that is why I wanted to see what others might have used and had success in using. Good read thanks

If this was my vehicle I would spend the money on an oil pan gasket and when I had the pan off I would pull the cover plate off the base of the oil pump and inspect it. It will give you an idea how much debris has passed the oil filter and gone through the oiling system.

If it has defined wear patterns and no deep scoring you could just replace the oil pump with a new one and feel comfortable that your idle oil pressure will be higher and nothing serious has gone amiss

If there is deep scoring in the plate you can be sure that some of those particles have made their way to a bearing or lifter. Only then would I contemplate going deeper into the engine. With the information you gave as to usage of the vehicle I would not likely do anything more than replace the oil pump.

Usually you can also remove the gears from the pump and inspect them.

Just be aware of the distributor drive shaft and its desire to obey the laws of gravity.

If your feeling cheap or want to pretend your a used car salesman just flip the scored plate over and reinstall it back on the oil pump.

I prefer to spend my money on physical solutions, not cross my fingers and hope solutions.
Just my opinions which have never gotten me a free cup of coffee anywhere!
