i got my inch pound from harbor for $15, works like it should, for $80 it better be digital. replacin the intake manifold is simple but of course ive done it enough times.
gaskets
180 stat
new bypass hose
maybe new temp sensor
Vaseline -injector o-rings-
2-3 gals of antifreeze
red or orange rtv
also make sure the first thing you do is take compressed air and blow out all the dirt between the intake n valve covers. if not the crap will fall into the lifter valley and its not good.
