For an 84 N5 with heads, $10-15k should be the price for the package. Going from a K2 to an N5 is a massive jump. As time goes along and repairs are needed, work on updating to the Hyperizing mods. Well worth the time and money. Engines were not much of a problem on the N5, but the 2500-3000 hr underhaul is well with it too. An 84 most likely has the long throat and will pick up much newer heads than the machine's age, making changing heads or trading much easier. Good luck!
