budget build 360

use springs that match the cam (manufacturer's recommended springs)
new oil pump (not used)
new water pump/hoses
fresh radiator (they get lots of sediment over the years)
heads all cleaned up, seats as previously posted, new valves (the 2.02's will be new of course, but the exhaust valves usually get pretty bad over time, so the new seats / new valves on the exhaust are a good idea)
also if it's an auto you will probably want a new torque converter / manual you will want a new flywheel / clutch disc / pressure plate since those are a major pain to change after the fact.

everything torqued 100% according to spec
all clearances measured and set 100% according to spec

new rod bolts, mains are usually fine but i wouldnt trust old rod bolts it's worth the $50 bucks or whatever for piece of mind. they take a beating.

get a book on rebuilding small block mopars. this will give you lots of pointers and tips for a reliable build that will serve you well for a long time.
i like this one but there are several available
