It runs good. No check engine lights. Coolant good except needs a flush. Oil good. No leaks. Fuel lines pressure good no leaks. Vacuum lines replaced.
Make sure to put a piece of tape around the fuel line return so when disconnected the nut doesnt slide into the belly of the beast. Two magnets on stick will retrieve it.
You could leave the intake manifold, injectors and injector rail on the head for easier removal.
Put the o rings on the injectors first. Coat with engine oil.
Put the wire clips on the electrical connection first then press the fittings together.
Dont disconnect the power steering or a/c system just unbolt them and move them to the side.
Drain the exhaust system since it might have a gallon of coolant inside.
Rotate the engine from the crankshaft bolt so the pistons are at the top of the cylinder to clean the carbon off.
