Greg, How many 1st gens are you going to buy ? I'm glad you found a nice one. No pics? Move the pump 1/8" or so towards the head, 366 govenor spring, full fuel screw turn in as far as you can with out runaway and also the afc housing. I don't believe any of this will hurt anything, just watch the egt's. Head gaskets may be an issue because of age. There are some good threads on here and the other forums as how to do these mods. Good luck with new truck. Thanks Steve B.
