Best way to start an engine after years of sitting

I have seen several discussions on how best to turn over/start an engine that has been sitting idle for many years. I came across a couple of discussions and this is what I have so far but a couple of points are unclear. Note that I have a 1940 356 engine but this could likely apply to all Packards.

1) pull spark plugs and fill cylinders with Marvel Mystery oil. Soak for 1 week.
2) disconnect fuel tank if it has not been cleaned.
3) drain oil and refill with 30W using the dipstick markings.
4) disconnect coil wire, leaving spark plugs out hook up battery and turn over engine
5) put plugs in and hook up coil wire
6) pour gas in carb
7) try to start

Here are some other steps someone suggested but I am not sure how to pressurize the oil system to get flow to the lifters which sounds like a good idea.
3a) remove valve covers
3b) pressurize oil system and observe oil flow through all the lifters

If there a way to spin the oil pump on these cars?
Someone else suggested buying a refillable pressurized container (eg aerosol) filling it with oil and hooking it up to the oil filter with the flow going towards the engine.

Thoughts?

Here is a pretty good detailed description of a process by Kaiser Bill:http://www.kaiserbill.com/Web-PDF/Start-Up.pdf
