Performing my first engine swap. Making sure I have a good sense of what it entails.

Hello everyone. I have a 1999 Ford Ranger XLT 3.0L V6. I've recently been dealing with some overheating and after some inspection realized I blew a head gasket. If I weren't so busy with graduate school, I would've taken the time to perform the repair myself, but as I don't have much free time I took it to a mechanic. He told me that there is serious rust and corrosion inside the engine and that my money would be better spent going towards replacing it, so that is what I am going to do.

Tomorrow (Monday the 22nd) I am going to order a remanufactured 3.0L (most likely from Surefire Engines unless this other company can match Surefire's price). My understanding of the swap process is this and it seems fairly straightforward:

1. Disconnect battery.

2. Drain all fluids from the engine and transmission.

3. Remove radiator and hoses.

4. Disconnect fuel lines.

5. Disconnect exhaust system from headers.

6. Disconnect all electronics from the engine.

7. Remove air intake hose.

8. Remove all accessories (belt, water pump, alternator, power steering pump, A/C pump, coil pack, etc.)

9. Remove upper intake manifold.

10. Chain engine to the engine hoist.

11. Remove nuts from motor mount.

12. Unbolt bellhousing from the engine (support transmission with a jack).

13. Remove engine with the hoist.

14. Swap all necessary parts from the old engine to the new engine (in my case it would be the oil pan, timing chain cover, camshaft position syncronizer, flywheel, clutch disk, clutch cover, and exhaust manifolds) -- The new engine comes with a new oil pump so I won't be swapping the old one.

15. Put new engine into the engine bay, connecting it to the input shaft of the transmission.

16. Bolt bellhousing to engine.

17. Tighten nuts to motor mounts.

18. Move lower intake manifold from the old engine to new engine.

19. Reinstall all accessories previously removed.

20. Using a drill, prime the engine with break-in oil (5W-30 for my truck).

21. After seeing oil coming out of the rocker arms and go back into the head, move old valve covers from the old engine to the new engine.

22. Install upper intake manifold, air intake hose, and coil pack.

23. Reconnect all electrical connections.

24. Reinstall radiator and hoses.

25. Fill engine and transmission with fluids.

26. Drive truck through periods of normal and aggressive driving, then change the oil at 50 miles, 500 miles, 1500 miles, and 5000 miles. (This part I am a little confused on. Should I be using break-in oil up until 5000 miles, or just for the first 500 or so? Or is break in oil just to be used on the first start up to operating temperature, then use conventional oil to 5000 miles).

27. Check all fluid levels periodically, specifically oil and coolant.

Any help would be immensely appreciated since this is my first swap ever. Thank you for reading this far!
